So I discovered about a 3"x3" oil soaked spot on my 4" Wildman Drago VK filament wound fiberglass nose cone. It was stored away and a small bottle of oil leaked out and soaked the nose cone for about two months. I tried to clean it several times with alcohol, but I can still see the spot. I'm worried that it is going to show through the primer and paint. I didn't know if I should just get a new nose cone and go from there. It looks like the oil is soaked into the fibers of the bare nose cone. I was planning on using automotive primer and paint. Any ideas? Thank you!
