When applying the first coat of resin to the mold, it won´t stick and i can´t make an even coat. When curing it starts to make voids in the middle of the mould. Probably because of the release agent. How can i fix this? I tried to make the part anyway and a got tons of holes in the surface like you can see in the photo.

or also nefrase that you cleaning surface after brushing as some bad things from cleaning cloth can be into that. BUT I KNOW THAT GOONA BE CLEANING BAD CLOTH! CHANGE AND YOU BE GOOD.
