8. Paint Area Manager and 25-year veteran of GM, Paul Durant, walked us through the processes of the paint area. This amazing area takes the raw metal truck and applies the many coatings that give it the right appearance and corrosion protection. The major processes include clean and prep (phosphate), electro-deposition (ELPO), sealer, prime and bake, liquid applied sound deadener (LASD), main color, clearcoat, and finesse (inspection, polishing, and so on). Here you can see a body being rinsed after it has exited the first tank of ELPO.
