WD-40 contains strong acids in order to penetrate rust. While it might not affect your skin much more than drying it out, it’ll absolutely damage a mold. Its thin viscosity means it won’t adhere to the sides of molds.
How do you keep epoxy from sticking to mold?
Still, there are many instances when you don’t want the epoxy to stick to one surface or another. The most simple fix is to cover your work bench with 3 mil or heavier plastic sheeting. It’s inexpensive and tear-resistant, can be taped to the work surface and cured epoxy will peel off it.

Can you make a resin mold out of hot glue?
Since cold hot glue doesn’t stick to anything you won’t need to use any other form of mold release. Simply fill the mold with resin and cure it. I cured it in a UV tank that’s meant to cure SLA prints but sticking it in sunlight for a few hours, or under a UV light for 30 minutes works just as well.
