Hi guys!
I've made the mould for my second piece of the project and its surface came out with a lot of imperfections.
I have sanded it but I took off some black gel coat in some parts, so now the polyester resin from the mould is showing up in some spots and the surface isn't decently even yet. I knew the plug wasn't perfect but the mould came out worse than expected.
Here are my questions:
1) can I continue to sand until I get a decently even surface, even though the yellow resin is visible?
2) do I need to re apply the gel coat and then sand it again?
3) I need to to even out the surface with bodywork filler and then apply the gel coat again?
I do not want to make the mould again, so which is the best way to do it in your opinion?
Many many thanks in advance!

Hi Tollaus,
These types of problems can be very frustrating and I know how tempting it can be to cut corners especially at the mould stage just so you can get on with the actual part. However time spent now getting the mould right will result in a much better end product.
It is all part of the learning experience and will help you in the long term to better judge what you can and cannot get away with.
Good luck and be sure to let us know how you get on.

Is it OK to bump this over to general composites as I don't think it relates directly to any of our products at this stage?
