I just noticed a drop of hydraulic oil on one of my molds.
It is a glass mold prepped with Zyvax Sealer GP and Frekote 700NC, used with carbon and Ampreg 21 epoxy resin.
Question is, is there any way to clean the mold without removing the sealer, I don’t mind the release agent as much as I usually apply a new coat of frekote after every release, but don’t want to go through the time consuming process of mold sealing every time something like this happens.
I wiped the oil drop off with a towel, but before I clean with acetone or similar I wanted to know if it would have to be re-sealed?
