Yesterday i went round to do it at 3, and he said there is no point using the fiberglass matt, so we used just the resin. HOWEVER the temperature dropped dramatically by the time we applied the first coat so it didnt dry, so i left a heater im overnight and its dried now.
Next weekend he has a gel top coat in a grey colour, im not fused about the anti slip additive as i barely walk in the back of my van.
