One for the board builders and artists amongst you:

I'm respraying a board at the moment. It has durable black 2k primer and a very light blue coat over the top (black almost showing through in places). I was wondering, what is the best way to get the 'brushed effect' that you see on board brands like Coreban/Focus etc? Obviously sanding is involved but what grade wet n dry paper and do you do it wet? Do you use a wood or a rubber sanding block? What sanding pattern? (presumably lengthways).

The plan is to polish the finish to gloss rather than leave it matt (like starboard) after I've finished.

Many thanks for any tips
