28 REMOVING PAINT Caution: Wear the proper safety protection when sanding, cleaning, mixing and spraying all materials included within this process. MECHANICAL STRIP Clean with the appropriate PPG cleaner. Remove paint with 80 grit. Avoid 36-40 grit disc because it leaves too deep of a scratch in the metal. PROS CONS • Removes old body work • Time consuming and surface rust • Labor • Safest way for do-it-yourself MEDIA BLAST The dry method is preferred and is becoming more popular. Should be sanded with machine 120-180 grit to remove paint (slight nibs) that can be left behind. To remove remaining rust, those areas will need to be spot sand- blasted or wire-brushed. PROS CONS • Safe way to remove paint • Does not remove rust • Will not pit or abrade metal CHEMICAL PAINT REMOVERS Aircraft strippers (Must be neutralized with water) Environmentally Compliant (PPG DURAPREP) PROS CONS • Best for original paint • Messy job, leaves metal smooth • Does not remove rust • Slow for cars with multiple paint jobs • Does not remove body filler Here are two links for more information: http://www.popularmechanics. com/cars/how-to/maintenance/ how-to-blast-your-car-parts- clean-15997905 http://en.wikipedia.org/wiki/ Abrasive_blasting 28
