How Long After Sheet Metal Rust And What To Do If A Car Rusts After Sheet Metal?

The face of the car is the sheet metal paint, and the main culprit of the rusty paint is the moisture hidden in the paint holes.

Solution: If it's just a slight scratch or rust, we can do it ourselves. Use very fine water sandpaper dipped in water to gently grind away rust, but do not grind in no direction, and polish in a straight line in the same direction.

Wait until it is completely wiped off and apply a layer of primer. New scratches were found and can be applied directly with a touch-up pen.

Use a wire brush or sandpaper to remove the paint from the damaged part, and then decide whether to replace the entire sheet metal part or repair the damaged part according to the degree of damage. If the damage is severe, it is best to replace the block in one piece. If the damage is minor, remove the corroded and loose metal.

Zinc sand is suitable for filling large holes, cut the zinc sand to be about the same size and shape as the hole, and then stick it to the hole, the sand edge should be lower than the surrounding sheet metal part, and then the filler is smeared around the sand, and then the filler can be filled and repainted.

Precautions for automotive sheet metal.

Try not to get wet in the rain or wash the car for 1-3 days after repair: sheet metal painting.

In the future, the paint has not completely dried, and if it encounters water, it will affect the paint surface, so try not to touch the water for the first few days, and wait for the paint to dry thoroughly before washing the car.

Avoid direct sunlight for 1-2 days after repair, try not to use: the paint is not dry, we will use it, sunlight, engine heat and other temperatures may crack the surface of the paint. It is best to place the car in a ventilated, cool place to dry naturally.

In this case, there is basically no sheet metal master or paint master to deal with in actual maintenance, the reason is nothing more than two points: first, labor-intensive, time-consuming and time-consuming, the anti-rust process on the other side of the fender or door sheet metal will definitely be damaged, but to deal with it, it is necessary to disassemble the front bar, headlights, fenders, and doors to disassemble the door lining, and the treatment can be sprayed or directly sprayed with anti-rust coatings such as chassis armor. Second, the significance of this kind of local treatment is actually not much, because it is the other side of the sheet metal parts, it is basically in a closed space, usually not easy to contact the water, even if the rust is very slight, even if the rust is not visible on the reverse side, it does not affect the appearance, so there are few treatments, and it is also thankless for the repair shop.

Hello, if it's outside. You need to re-paint, if it is inside, buy a bottle of self-spraying paint spray anti-corrosion.

Originally, according to the manufacturer's training teacher, if you don't scrape the ash for two hours, you have to apply epoxy primer, but I have walked so many places, and I have never seen an epoxy primer. Whether it will rust or not is also related to the scraped ash, there is putty ash, and sheet metal ash.

Sheet metal ash *** some, strong adhesion, after scraping the ash to polish, there are dry grinding and water grinding, dry grinding *** some, after grinding, some spray primer, some scrape fill eye ash, spray primer good point.

This is due to the fact that in the process of sheet metal shaping, the anti-rust material on the metal surface is destroyed, and in this case, even if the anti-rust material is artificially sprayed in the later stage, its adhesion, including its spraying environment, leads to his ability to waterproof and isolate the air, and the performance of the original car is better. So after a period of time in Beijing, there is a possibility that there will be rust.

First of all, sheet metal is not 100% rusty. After the putty is polished, it will not rust as long as it is painted. If hot work (such as welding or cutting) is involved, rust will occur in 2 to 3 years.

The high temperature has destroyed the anti-rust paint inside the sheet metal because it destroys the inside of the steel plate and the paint coating, and the inside of the body will start to rust. If the vehicle is humid and humid, it will rust in advance.

Under normal circumstances, it is necessary to do anti-rust treatment on the other side of the sheet metal, but for cost considerations, most stores will omit it.
