Assuming you are using West Systems epoxy resin for your lay up? That is ethanol resistant anyway.
There are lots of products to adapt the base resin to many tasks. You can thicken it to a paste or even putty like consistency with flocked fibres or micro-balloons, there's an inert powder that can be used too, but damned if I can think of the name of it. It turns the resin a sort of greeny-grey. Your composite supplier should know all about these fillers.
You might even be able to make a sort of gasket, such that you experimented with before, using core mat instead of a filler admix, but that's going to be messy!... Do take photos though..
