Leave for a couple of hous at least then repeat!! Hope this helps?? Kind Regards The Fibreglass King

Now I'm thinking I will spray 5-6 coats of PVA then give another try with the gel coat. Edited 11 Years Ago by BlackNDecker

You better do a small experimental mold first, I am not sure this will work. The uni-mould system uses a vinylester tooling gelcoat and both the coupling coat and tooling resin are polyester based. I am not sure the West will properly bond to them. [Edit: typo] Edited 11 Years Ago by brainfart

Obviously different combinations though, so I would also recommend doing a test first. However, if you've got the polyester resin, why not use that?
