Hello,
I recently did some molds from an epoxy aluminiun resin vac cast from easy comoosites…and at the surfase of the mold there are a few holes i would like to fill…is there any material like a paste which is capable of that? The mold will be used for prepreg so it will be heated in 120 celsius
Best to use the same material you made the mould with. I would use the aluminum epoxy surface coat to fill, post cure, then sand and polish
