AeroMarine Casting Resin is a polyurethane polymer that frequently exudes an oily film as it cures.  This film seems to dissipate a day or two after curing.  It is also possible to prime the casting resin with Krylon Fusion spray paint before applying any other paint.   If possible, let the object cure for a couple of days, then wipe with a paper towel.   In some cases you may need to wipe the casting with a mild solvent or alcohol to remove any surface oils.

Some used paint the inside of the silicone rubber mold before casting the resin.  The resin then sticks to the “back” side of the paint. This has the advantage of creating a chemical bond between the resin and the paint.
