    Polyester Colour Pigments are added to resins and gelcoats to provide a deep uniform colour. The pigment dispersion resin is a non-reactive resin and can act as a plasticizer so no more should be added than needed. The best way is to add small amounts, starting with 1%-2% and increase as required. Dark colours will require 5%-7% addition.

Fillers and additives can be added to Polyester and Epoxy resin to extend the resin and impart specific properties to the resin mix. The amount of filler that can be added depends on the viscosity of the resin and the size of the filler particles, generally, the smaller the particle size the less filler can be added to give a workable mixture. It is best to add fillers and additives just before using the mixture to minimize any settlement that may occur.

Our Easy Sanding Body filler, manufactured by ProWorx is the best in its class for automotive repairs. Suitable for a deep fill, this body filler cures quickly, pinhole free and as the name suggests, is super easy to sand.
