To check this, I took a scrap of raw plywood and soaked it with WD-40 and let it dry for 7 hours. Then I sprayed it with polyurethane paint. The paint I used will fisheye like crazy on fiberglass that has come in contact with silicone based mold release. I know, I have sanded! An hour later the wood is still damp with the WD-40 and the paint is skinned over but it takes 24 hours to really dry. But no sign of fisheye. Don't know what I could have done to make it fisheye other than what I did. Still no guarantee that it will not fisheye in your application. Now I may go fishing and spray WD-40 on my lures. That is supposed to make them catch more fish and it sounds like a test that would be more fun.
