what do i do with cracks in my mould

I think its because i had to be a bit aggressive getting the mould of the roof

There are also some very fine cracks which the camera wouldnt pick up

How do i fix them as it was an expensive mould and i dont want to scrap it

i think what joe said was exactly what i always do but before adding the gel coat to the crack u diged i put a normal paint paper tape around the crack so i wouldnt mess arround so i wouldnt need to sand more than i should , if u want something more strong and faster, i put normal epoxy the two that u mix together ,it works and can be sanded and polished too.

also you can add a layer of pva (2 layers) which will result in fast release.

hope this will add an idea. also as joe said this is a way i used not an exact expert how it should be done.
