I purchased a well used boat on craigslist last month and since then I have repainted the boat. I realize that I need to put some type of protective clear coat on top to help fight against scratches in the paint, are there any specific type of coating I should look for. Again, this is a Duck Hunting boat, so a Matte Finish would be ideal... and even though the boat will be mainly used for duck hunting, I am very pleased with my paint job so I would love to try and preserve the look for as long as possible. Thanks for your help.
