3 Craig uses two different fillers, both from Evercoat. In the welded joints, or the lead wells, Criag uses Everglass, a short-strand, fiberglass-reinforced body filler that is waterproof, making it a perfect product for these areas. For the other areas of the car, Craig uses Rage Xtreme. This stuff has self-leveling properties for easy spreading, which reduces the sanding time needed to remove heavy texture. Speaking of sanding, the Everglass was shaped with Klingspor 40-grit paper, and the Xtreme was sanded with Klingspor 80-grit.
