Specialized automotive paste for the repair and reconstruction of plastic auto parts such as: faces, grills, spoilers, skirts and boards, integrating adhesion promoters, plasticizers, polymeric elements as well as fiberglass in filaments and micronized. Polymeric elements promote superior adhesion on plastic surfaces such as PP, ABS and other plastics and help generate a smooth surface when sanding. PLASTI-HAIR can repair ruptures, cracks and holes in facias, arch moldings, spoilers, boards, interior and exterior plastics. PLASTI-HAIR can reconstruct missing sections or create new sections in a facia like a sports air intake, a headlight graft, and more.
