After doing a bit of carbon fibre skinning on my motorcycle I was pleased with the final result but after I washed the bike a few times it seemed to leave behind some water marks within it.
I sanded the part down again and then decided to lacquer it and that solved the problem but I didn't think I would have to do this?
I thought that once the resin had cured it would be water proof so I don't understand why it has done this, can anyone explain why this has happened.?
