Auto Paint Removal Instructions

When it comes to cars, paint removal isn't something that is thought about much. There are several ways to remove paint from a car's surface, but only a few should be attempted by non-professionals. Some paint removal methods can damage the metal surface of the car if not performed correctly.


Removing Paint by Sanding


To sand away old paint, primer and body filler, use a dual action sander. A dual action sander combines orbital and random motions at once, so paint is quickly and completely removed in a short amount of time. The sander is gentle on the metal surface and won't cause gouges or deep scratches. An air compressor with at least five horsepower is also recommended. Make sure to wear a dust mask while sanding, since the sander will cause dust to fly around the area.


Use 36 grit sandpaper with adhesive backing on the dual action sander. Use the sander against the surface of the car to quickly remove all paint and primer. Don't put the sander on any chrome, plastic or glass areas because the rough grit of the sandpaper will cause damage to those surfaces.


A dual action sander can be used on any type of metal surface, even soft aluminum.


Removing Paint with Chemicals


Chemical paint removal is less labor intensive than sanding, but can be dangerous because of the chemicals and fumes involved. Before applying the paint stripper, park the car on a flat surface with a large tarp underneath it. This tarp can catch the stripper and the old paint that comes off of the car. You can roll the tarp up and dispose of it properly.


Begin by using a paint brush to apply the paint stipper to the car's surface. The car may need a few coats of the stripper applied to remove all of the paint. You will need at least four or five gallons of paint stripper.


Allow the stripper to sit on the car for one hour and then begin to scrap the paint away using a plastic paint scraper. The paint should come off quickly and easily. Once the paint has been removed, rinse the car with cool water to remove any remaining chemicals from the surface.


After Paint Removal


Once you have removed all of the paint from the surface of the car, the bare metal is left exposed and vulnerable to rust damage. Rust can adhere to a car's surface in less than 24 hours in some climates. You must take a few steps to prevent any rust from forming, or risk damaging any future paint jobs on the car.


Wipe the car down with a metal conditioner and microfiber towel. Metal prep is available at any hardware or auto paint store. Wipe the metal with the metal prep, rinse with cool water and allow it to dry. Spray a coat of primer to the car's surface to seal it and keep rust out. This primer can be easily sanded away once you are ready to paint the car at a later time.
