Surfing Waves

Hey everyone, long time lurker first time poster.

I have a Ben Williams board that had some damage and cracks. I fixed all these with glass and epoxy and have painted the board using a base coat of white Behr acrylic paint/primer, then did the color design with acrylic Walmart paints. Everything is curing now and I am trying to figure out the finishing coat.

I have a can of Krylon acrylic triple thick clear, a can of two part 2K automotive clear coat, and a plentiful amount of epoxy and hardener. When dealing with the top coat I am concerned about its long term durabilityz specifically in regards to scraping wax off the board/being in the car. The Krylon is the cheapest option and I have seen it mentioned a few times around here, but will it stand up to regular use? Of course, hitting the board with a layer of epoxy and sanding it smooth would probably be the most durable, but is all the work necessary?

Looking for any advice. I'll get some pics of the board loaded up as soon as imgur stops breaking.

Careful if you go with the acrylic i think it smears/mixes with certain types of paint if i remember right. Had that happen with one of my boards and it just kinda liquefied the paint job i had laid down when i sprayed the acrylic on

I used clear urethane on a board, 3 years later it's still good, but I it does add a little weight cause it is viscous

I ended up going with the Krylon clear and it seems to be okay. Main problem was the xxxxx spray cans don't have much volume output and the spray pattern is pretty small. If I could do it again I'd use something I can paint on.
