For sure my baby needs some help. I tried some rust mediation on my door bottom seams. I scraped all the loose rust off and coated the areas with a rust neutralizer to try and stop the oxidation.

Then I tried to seal the areas with a spray on rubberized paint from the auto parts store. I wanted to spray the bottom seams of the doors and tailgate as well as a few inches up the sides. This is what I tried, but may have to redo a door. I did not get it sealed well. Lifetime Member.

City Pine Island State Florida. Without seeing the condition of the rest of the Truck and it's running gear Dick. I would how to cook menudo in a pressure cooker securing some good Florida Arizona would be even better used front doors that are not all eaten alive with rust.

This and just have them repainted to match the rest of the body pending the condition of the rest of the Truck? That is a hard area to correct for such and stop it from going forward once it how to start with embedded linux And you need to ensure that those door drains are totally clear part of the reason why they are in that shape so our Summer daily rains here in Florida, just don't accelerate that rusting out process Scraping off loose rusted metal and just spraying paint on it I fear, it is just a Band Aid on a Bullet Hole.

And in the Big Picture IF you plan on hanging onto her for years? Then she needs some good used doors installed and then just re-shoot the entire truck to match Sill from what I can see thus far more cost effective than getting a new Truck for sure!

Going forward and for the benefit of other Members You need to check and ensure that your door drains little rectangular or round holes up from the bottom front what are the mlb teams back on each door are totally open, this so water can quickly drain out from inside the door where the windows retract into. Simple process really of just opening the door to check the drains with a wooden skewer or zip tie, and clean the drains as needed.

The inside of the door panels are good. The problem is that where the door skin folds over at the bottom the weld along the edge started rusting and it got under the paint for the length of the door. If I can stop it before it breaks through I can increase the life of the door. From the look of the pictures above, not only does the door skin where it folds and is welded have issues, which is expected since that areas stays dirty and holds moisture unless addressed But, I also see areas of rust and bubbled paint on how to play the piano books bottom of the door above that area, near where the window retracts into the door Pending how high she sets off of the ground, I would grab some safety glasses and lay on my back and really clean that area and get it all dry again.

Then I would attend to the metal issues to help arrest that rust If not, the heat, moisture, salt air and rain will really make it take off and spread like a cancer for sure This ain't the Midwest so it's not like driving in Bay water months out of the year! But our Tropical weather unlike the desert Southwest, can really fan the rust fires for sure! I guess I should find a way to get as close as I can to bare metal everywhere below the weather what does chow bella mean in english and go from there.

I does sit pretty high off the ground, but I would use a face shield to keep it out of my nose and mouth as well. The other item I saw in the pictures was the condition of the frame rust and I suspect other parts like the exhaust. You might want to try the same process for cleaning off the bottom of the boat and trailer from saltwater, and also use a lawn sprinkler placed under the truck for a while, too really wash out all the left over road salt to help slow that process down And if you have a pressure washer?

You may want to consider getting one of these not only for the truck, but the boat trailer when it gets dunked into saltwater to really flush it out quickly As mentioned before, I am testing a new product formulation from our friends over at Dynovatech that is not on the market, and does not even have a product name just yet As soon as I can secure that information though I will be happy to share it!

In the mean time, I am sure you could get some of the same results from BTS. Daveas you infer prevention is the best way to avoid the door rust issues I am working on. My first attempt at the rust on the doors seems ok but I do need to get more of the rust out of there then seal it up.

To that end I got a spot blaster from Harbor Freight. It is a cheap tool but is doing a better job at getting the rust out. Although I may want to look for a more aggressive media than the black aluminum oxide I have been using. Great idea and I like that tool!

I would just get it clean, and then apply a quality rust converter and then follow up with the paint type of your preference meaning Flat, Gloss, etc. Looking forward to the "after shots" on this project for sure Brother! Well I did the tailgate seam for practice and learn workable pressure setting for the media I am using.

I used a wire brush to get off how to prevent pollution ppt loose rust and paint. Then a metal scraper to make sure everything left was firmly attached. I then blasted the areas until everything was shiny metal. I sprayed rustoleum rust converter to get in all the tight areas and convert any missed rust to a paintable surface and seal it to prevent further.

I then use Rustoleum spray on truck bed liner to further seal and protect from further scrapes and damage. I think I will wait until I get south before I go over the door seams again and work on some of the supports under the bed that need some work.

Looking good Brother! So how has the project progressed Dick? Door seems looking better now? Pictures please They still look better than when I started. But the rust has started coming back. I guess i will need professional body work on the bottom of the doors.

City Colonial Heights State Virginia. Holy smokes! What year is that f? I've got a FX4 that is still tight as a tick. My model year is how to stop rust on bottom of car door for leaks around the third light and sunroof. Ive replaced the OEM gasket in both back around 7 years ago. The Canada made fs have had a huge failure rate in the the 3rd brake light gasket which transfers down into the door panels. Luckily, mine was a Kentucky girl.

Knock on wood, I've got zero rust on her. I've owned 4 trucks and this 5. Now AC wise, its garbage. Only caveat I have with this truck, the AC has been absolutle crap from day one. The cab has never been below 80 degrees in summer. Total schit design, and they knew it. Only caveat I have with this truck, the AC has been absolute crap from day one.

They're known for being crap. Best low temp I can get out of the vents on a 90 degree day is 70 degrees even with recirc how to stitch baby clothes. Otoh, my work dodge is a ice box in 60 seconds in the same situation.

Oh I agree!

The only permanent cure I have found is the use of Miracle Paint. This super tough coating loves to stick to rust and forms a permanent moisture barrier to stop rust in its tracks. Remove your door panels and coat inside the door bottom about 2 inches up from the drain holes. Jul 14,  · In this video I remove rust from my Chrysler m door jams. This is not meant to be a professional fix, but is just meant to slow the rust process. Tha. Sep 08,  · The simplest way to deal with rusting underneath your car is to prevent it from happening in the first place. The best way to do that is to coat the exposed metal beneath your vehicle to keep water and salt from coming into contact with it.

An ominous brown stain on the fender. A bubble in the paint at the bottom of a door. Soaked floors after hitting a puddle. These are signs the iron worm has been hard at work: rust. With iron-based metals, battling oxidation can feel like a Sisyphean task. In fact, iron and most steel will completely reduce to iron oxide and other constituent elements over a long enough time.

This doesn't mean that your car is doomed! Rust forms as a result of the electrochemical breakdown of iron-based metals. This breakdown is the result of oxidation, which is the process where iron surface molecules react with oxygen in the environment and produce a new molecule, Fe2O3, otherwise known as iron oxide.

That iron oxide is rust. Pure iron doesn't oxidize as aggressively. Examine an old iron engine block and you'll see a thin surface layer of rust but little penetration into the metal. Adding a dollop of carbon to iron creates steel, which offers dramatic improvements in flexibility, tensile strength, and formability. However, this added strength comes at a cost, as it adds impurities that accelerate the formation of rust. Exposed steel rusts at different rates depending on several factors: alloy components, thickness, the environment the steel lives in, and the type of heat treating the steel undergoes.

Very poorly made cars in the s began showing surface rust as soon as they hit the docks. Completely untreated raw sheet steel can rust through in as little as a few years. Road salts and other contaminants dissolved in water act as electrolytes. When electrolytes are introduced to a chemical reaction, they speed up the exchange of molecular components. For drivers, this means that dirty or salty water trapped somewhere in the car's body makes that spot rust faster. It also explains why cars in northern climates where salt is used in winter as well as cars that spend a lot of time near the ocean are prone to rot.

This is why automakers do so much to try and prevent corrosion. A huge amount of testing and material science is dedicated to keeping your car from dissolving away beneath you. Aluminum and magnesium components are becoming popular not only because of their light weight, but also because they corrode at rates that are unnoticeable within a human lifetime. However, those metals are expensive and automakers use them sparingly as a result.

Modern sheet steel also comes off the roll with highly durable coatings. Those are further augmented in the final assembly plants when freshly made vehicle bodies are dipped in baths of anti-corrosion agents before the painting process. However, the road-facing side of the car turns into one big sandblasting cabinet at highway speeds, and those dips and coatings wear off over time.

This is why every car owner needs to periodically inspect their car for rust regardless of where it lives or what kind of additional underbody coating it may have come with. Rust forms in stages, and knowing where a problem spot is in that decomposition process can help point you to the right solution. Here are the three main stages of rust and how to fix them.

The first signs of a problem pop up in paint nicks, cracks, and scratches. An easy fix. Surface rust is just that: on the surface.

Leave a car with steel disc brake rotors parked for a little while, and you can see surface rust form on the rotors. Most surface rust on your car forms when paint breaks down through mechanical or UV damage, which is why even cars in warm, dry climates get it. Structurally, surface rust is not a problem, and depending on the metal's thickness and alloy composition, a level of "passivation" may even be reached where the surface rust actually guards the metal from further oxidation.

Regardless, it's best to correct surface rust as soon as you see it—just in case. That patina-coated truck from Arizona may become a hole-filled nightmare in the wrong weather. The fix is much like general paint repair. Start by using an abrasive wheel or sandpaper we used grit to cut through the paint and corrosion until clean, bright metal is visible.

Rough up the surrounding areas, too, so that your body treatments can adhere well to the car. Next, use a rust inhibitor or converter to impede the tin worm's progress. Rust inhibitors convert iron oxide into a chemically stable, moisture-resistant compound that protects the rest of the metal underneath.

For example, the Permatex Rust Treatment we tried contains tannic acid, which reacts with the rust and converts it to iron tannate which is stable and 2-Butoxyethanol, an organic polymer that acts as a primer atop the metal. Then put on some rubber gloves and apply the rust converter with a brush or sponge. You'll want to pour as much rust converter as you think you'll use into a disposable container because you can't double-dip into the bottle.

Wipe a thin layer of rust converter onto the metal and wait 15 to 30 minutes for it to dry. Then add a second layer and wait at least a half hour for it to dry. If you can keep the surface moisture-free for 24 hours, then you could prime it—this Permatex Rust Treatment isn't a primer for paint. Follow up that primer with paint and clearcoat, then buff to blend the finishes.

This is because iron oxide molecules are physically bigger than those of iron or steel. That worsening rust issue self-propagates by expanding and flaking away the outer layers of paint and metal, exposing fresh base metal, which then corrodes. When rust penetrates into the surface like this, it causes a rough, pitted type of damage called scale. Correcting scale means getting through the rust with a wire brush, knocking down roughness with a grinding wheel and smoothing out the surface with sandpaper.

Rough up the area around the bare metal so your next sealants and treatments can stick to it. Follow the instructions from the manufacturer of the body filler as it can vary, but generally speaking, you mix it up to a specified ratio depending on your room temperature.

Spread it on using a metal or plastic spreader, but leave a little extra on top to sand smooth. It takes about 30 minutes for Bondo to fully cure and harden. After that, smooth out the extra filler you left on top so the repair matches the contours of the rest of the car. If you have a rust inhibitor that is safe to use with body filler, add this now, but otherwise, you can seal your work with a regular, high-quality primer.

As with fixing surface rust, paint and clear-coat your repaired spot, then buff to blend it in with the rest of the car. After prolonged exposure, steel is converted to brittle iron oxide and holes form. Take a look underneath the car periodically to inspect for any rough or compromised parts that could be a safety risk on the road if left unfixed.

As scale rust gets worse, the base metal flakes away and leaves holes. A reputable body shop should be able to take care of either issue.

Welds that hold on patch panels can be smoothed out to look like they were always part of the car by the right set of talented hands. A rusted-through frame means the structural integrity of the car is questionable, and it should be inspected and repaired by a qualified repair facility.

The good news is that this kind of vehicular decay is largely preventable. The best advice is the most obvious: Wash your car regularly to keep the body and underside clean of the road grime, salts, and dirt that lead to corrosion.

Many modern car washes can blast the underside of your car with water to get much of this grime off. The not-so-obvious advice is to check the drain holes along the bottoms of doors and rocker panels, which allow rainwater to flow out. WD can be a useful tool here as well. This lubricant protects parts from corrosion, and its thin nozzle can be used to reach tight underbody spots and blast away water or corrosive grime. As noted earlier, many vehicles have a thick coating on the underside that chemically seals the steel against oxidizing agents.

Regular inspection and repair of the spots that have worn bare will keep rust from advancing and causing additional damage. If this coating is not there, consider adding one yourself. POR is one of the more popular examples of such a rust-protective sealant, and they even have a rubberized coating to go over it in case you want even more protection underneath your car.

As with other rust repairs, sand off any rust that might be sticking through and rough up the area you intend to paint with some sandpaper, then brush or spray the new coating on. As long as your metal is properly sealed from the elements and kept clean of corrosive salt and grime, you should be able to get years of safe driving out of even the most abused winter beater.
