Our Putty additive is a blend of fillers that will give you an easy to work additive that will stick to your part, not your hands. Add chopped fiberglass to make a reinforced mold backing for odd shaped molds.

Use for small mould backing, odd shapes or in the corners of bigger molds where your chopped strand mat won’t sit down (Apply into your sharp corners before your chopped strand mat to avoid voids).

Mix at 3-4 parts filler to resin.
