Imperfect mould surface.

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!

The mould is used to produce several prototypes, so at this point the finish is not "that" important, but I would still like to get e decent piece without having to make the mould again. I knew the plug wasn't perfect but for some reason the imperfections came out much worse than how they appeared on the plug and the mould is now full of humps and bumps which I would like to even up a bit. In case one gel coat layer is not enough to smooth it out, is the use of a bodywork filler plus another gel coat layer a good move in your opinion? Thanks in advance.
