Milled Fiberglass and High-Resin Formula Makes for Smooth, Sag-Resistant Reinforcement
Featuring a combination of malleability, smooth fill and ease of application, our 3M™ Milled Fiberglass Body Filler features milled, chopped strands of fiberglass which make for excellent reinforcement during auto body and marine repairs. This fiberglass filler is formulated from polyester resin/styrene base, ideal as a build layer where thicker applications of body filler are needed. The two-part formula delivers exceptional gap bonding and sag resistance on larger holes in metal, fiberglass and SMC.
When properly mixed, applied and cured with hardener such as 3M™ Cream Hardener (PN 05766), 3M™ Milled Fiberglass Body Filler is waterproof, extremely durable. It acts as a reinforcement and readily accepts body fillers for final shape and featheredge.
