Presto Polyester resin Prestolith Special is an elastic, highly reactive unsaturated polyester resin suitable for a wide range of surfaces including metal, wood, concrete and fiberglass fabrics. Its easy‑to‑mix formulation provides excellent adhesion, high elasticity and quick curing with a working time of about 10 minutes at 20 °C. The resin can be sanded after roughly 40 minutes and withstands temperatures up to 120 °C, making it ideal for automotive repairs, boat building and model‑making. For best results, apply the resin to a clean, dry surface and finish with a compatible topcoat.
