Two-pack, or 2-pack, paint is a versatile automotive paint that holds a number of advantages over other traditional varieties. Two-pack paint is professional-grade and is highly resistant to gasoline, acid and sunlight, making it ideal for classic car restoration. The paint also requires complete removal down to bare metal because of unique properties that prohibit it from melding with any other primers or thinners.
Mask the areas of the vehicle that do not need the paint to be removed. You can also temporarily remove the targeted body panels if possible; attempt this only if you have access to the proper method.
Protect your skin with solvent-resistant gloves and cover your face with a dust mask. The hardener in two-pack paint as well as the paint stripper are both highly toxic when inhaled in excess.
Prepare the chemical stripper according to the manufacturer's instructions. Brush an even coat onto one manageable section of the sheet metal at a time and allow it to set for the waiting period indicated on the product label.
Begin carefully lifting the paint with a stiff putty knife or paint scraper. Repeat this process with each section of the vehicle until as much of the two-pack paint as possible has been stripped.
Wear protective eye goggles and use a dual-action power sander to remove stubborn primer coats that are not always affected by chemical solvents. Wet the vehicle and set the sander on "strip" mode; apply only moderate pressure as you sand the surface in order to avoid marring the underlying metal.
Set the sander on an "oscillate" mode to remove any swirl marks or minor scratches that may have resulted from the previous sanding cycle. Dust the vehicle to remove residue and rinse it thoroughly in preparation for a new coat of paint.
