smoothing corner radius and gelcoating problems
Is there a good method of smoothing fillets and radiuses made using plasticine in the corners of a one shot mould? They look pretty smooth but when you remove the part from the mould after gel coating and glassing they are not very smooth at all, and require a lot of sanding and filling. I also have trouble getting the gel coat to cover the plasticine, should I be using something else instead of plasticine. The mould is made from melamite and only needs one coat of wax to release, for this reason I did not spray the mould with PVA but maybe I need to coat the plasticine with PVA. Regards Bruce |
