CRC Plastic Putty is an all purpose, versatile, fast curing, medium weight polyester filler. It gives an extremely high quality finish for general body filling on a variety of surfaces.CRC Plastic Putty supersedes other filler compounds because there is no shrinkage. It is smooth and easily applied, with exceptional adhesion. It cures by a chemical reaction so it will not shrink like common air drying fillers. The special formulation will prevent sagging and pin-holing. CRC Plastic Putty cures tack-free, and is compatible with basecoat/clearcoat systems, eliminating staining and/or bleeding of basecoat.
