Any suggestions on how to go about this, its an old board that i just fixed the edges on and have sanded down the whole board. But what primer should i use? and any ideas on some nice color combos? Thanks!

you might try the wakeboarding section I think I read a couple posts of people doing this

Dude, just sanded it a little and use spray paint with some stencils. Give it that ghetto look.

Yeah, don't get too involved with it, just prime it and rattle can it - whatever work you do will not last more than one season.

I painted one for a good friend at the begining of the season. I used automotive primer, base and clear coat. I didnt spend a million hours on it cause i wasnt sure how it wold hold up. It was an older board he loved that was beat up and the shape is not around anymore, and just wanted a face lift. After a season of riding every weekend it has held up fairly well. We always laugh at how many people comment on it, most aking what kind of board it is.
