USC® GOLD (FORMERLY AU79™ ADVANCED LIGHTWEIGHT FILLER)
A premium filler with Invisix™ micro-perfecting surface technology to deliver amazing surface and sanding properties (no pinholes!). In addition to excellent sanding and featheredging, this filler is multi-purpose–great for vertifical repairs and adheres to all metals.
Use to repair dents, dings, scratches and hail damage (up to 1/4” deep). Can be used on steel, aluminum, fiberglass, wood, other body fillers, 2K primers, aged and sanded OEM topcoats and SMC for cosmetic repairs, and galvanized and other zinc-treated steel. May be topcoated with polyester, 2K urethane or 1K primer.
For a 4” diameter puddle of filler, add a ribbon of cream hardener from edge to edge (or 2% by weight of filler).
