ive got my boat sanded down a layer, i was initially going to primer the boat then spray the topside with an automotive 2 stage paint. (the paint was free) after sanding it smooth and filling in the gouges ext.. i realised i never needed to sand through the original gel coat, so there is no bare fiberglass exposed.
do i still need to lay down a high build primer or can i just spray the paint overtop of the sanded gel coat and expect a similar quality?
