Hopefully not? The flanges are just flat and have some location bumps. Does anyone have a clever temp trick for sealing my flanges? It's a wet layup epoxy job. Maybe just a bead of epoxy glue in within the flange would be thick enough to stop any flow? Or maybe an automotive gasket goo? Fastacraft Facebook page

I have had a silicone issue in the past where I cast a silicone part in a frekote mould and it stuck permanent. The flanges are also waxed but Id still rather not use silicone. I might try some small tests with PVA glue or clag craft glue? Fastacraft Facebook page Edited 9 Years Ago by Fasta
