Gelcoat is a top coat resin containing fillers and pigment. The fillers allow the gelcoat to spread in an even layer across moulds. Commonly brushed on as the first layer within mouldings which once turned out, will become the top layer.
Gelcoat is available in 1L or 4L and comes in a variety of colours.
Gelcoat requires Catalyst MEKP at 2% to enable it to harden (SOLD SEPARATELY).
