I finished painting the stand last night and I am going to let it cure for about a week before I set the tank and get it wet but before I do that I have a question about using polyurethane or some other sealant on the top where the tank will sit. I use the polyurethane on the corn hole boards I make and it drys fast and holds up well. My question is, what are y'all using or is an extra coating even necessary on the top? FYI: My biggest concern is the tank eventually sticking to the paint. (I will post pics of the finished stand when I get home today.)
