I have a vintage wooden boat my father built for me back in the '70s. It was a nitro boat, last run in 1992 or so. I am refinishing it and just completed sanding off the original paint. I am planning on using a more modern approach to finishing the hull, specifically laminating with fiberglass/epoxy prior to epoxy painting. Once done, the hull will be converted to electric. On the side where the original engine exhaust was located, parts of the hull look to be soaked with remnants of the fuel. I am assuming it is primarily castor oil, but could be wrong. I noticed after stripping off the paint that the oil was beginning to wick through to the freshly sanded side of the hull. Are there any recommendations on how to deal with this, is it a big issue or are the epoxy laminating steps good enough where I wouldn't have an adhesion issue?
