Hi all!

I´m doing my first jobs in carbon and i´m having some problems.
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.

Any help would be appreciated.

Thank you!

I had similar problems.




I got my best results by changing into vinilester clear gelcoat. It´s made for that use and simply doesen´t open. In a second term it cures in about 30 min, and so there is Little choice/time to open...
