You could say that rust particles are like cancer cells that spread on its carriers when left unnoticed and untreated. They are an unwanted and unhealthy nuisance to anything that contracts it. The rust on your car is no exception, and is not simply caused by normal wear and tear. More significantly, rusting occurs when deep scratches expose the metal underneath to moisture and air. When your car paint gets chipped or scratched through the primer coat, the rust spot spreads over time as the base metal oxidizes.
Taking care of small rust spots on a car is easier than most people think. Once they start to pop out, they should be dealt with immediately. Because if these rust spots are left untreated, they won’t stop spreading until your car has completely deteriorated. You sure don’t want this to happen, right?
Here are some steps on how to treat and eliminate rust on your car:
1. Prepare all the materials needed: brush, sandpaper, scraper or knife, alcohol, car paint (exactly the same colour as your car’s body), cloth, primer and paint protection spray. When in doubt, you can go to any reliable automotive store, where you could seek assistance from the sales attendants.
2. Clean the rusted area by dipping the cloth into the alcohol container. Scrape off any loose paint out of the vehicle using the scraper or knife.
3. After the spot has been cleaned, rub it with even pressure using a circular sandpaper. Sand away until it is completely free of rust. Failure to eliminate all signs of rust would result in the eventual return of the rust.
4. Brush off any dust or particles from the surface. Be careful not to touch the area with your hand, for the oils from your skin can stick to the surface, which will make things difficult for you when it’s time to apply the paint.
5. When the area is smooth, apply the primer underneath the actual finishing paint. The tip here is to tape off the area you’re working on to prevent yourself from painting over the original paint or the non-affected area. Add about three or four layers of primer. (Common sense tells us that we should wait for the surface to dry before we add another layer.) Let it sit for a day or two. Don’t forget to remove the tape after painting in Step 7.
6. Grit the affected areas again, this time with a finer sandpaper just to ensure that there are no bumps or rough areas left.
7. Now, spray on a thin coat of paint for the finishing touch. You may layer as many coating as needed over the primer to grant your car the “brand new” look. Again, allow the paint to dry before continuing to top it over with another layer. Impatience may cause it to look dapped, dripping with excess paint.
