I've been putting off refinishing the deck on my 18 foot center console for a couple years. Up to now, I would scrap off the peeling paint patches in the spring and slop some gel coat on to get me through the season. I'd like to do a complete job this coming spring and hope you all can offer me some advice. Under the deck paint there appears to be a layer of fiberglass, there does not seem to be any soft spots or rot that I can find. Do I need to chemically remove or sand/scrape all the paint off? What type of primer do I put on the fiberglass? What's a good durable top coat that will last for several years? Thanks for any recommendations you can provide.
