Fiberglass Filler Putty — Heavy-Duty Repair Solutions from SYNEW
Fiberglass filler putty is an essential material for professionals who repair and refinish composite parts, automotive bumpers, GRP (glass-reinforced plastic) panels and welded metal substrates. Unlike light-bodied body fillers intended for small dents, fiberglass filler putty is formulated to provide structural strength, superior gap filling and high dimensional stability for large cracks, holes and deep gouges. It’s commonly used in collision repair, marine and industrial maintenance where both mechanical strength and a sandable, paint-ready surface are required.
Industry professionals choose a quality fiberglass filler putty for several reasons: it must bond reliably to different substrates (fiberglass, plastic, steel), cure predictably with minimal shrinkage, resist cracking under stress, and be easy to shape and sand so the repair blends invisibly into surrounding surfaces. Modern formulations frequently use polyester resin systems with peroxides as curing agents. Properly formulated fiberglass putties deliver excellent filling volume and maintain their shape during sanding and primer application, preventing the common problem of post-spray weld unevenness that leads to rework.
