Mark, <br> <br>I just sand the side trailing edges with wet sand paper (600 or higher) til you can just see the glass on each side. look at the glass on both sides and when it is even, about 1/16 to 1/8" wide all the way down the trailing edge you're pretty much there. Start your sanding taper about an inch in so the angle isn't so great at the trailing edge. This is with boards and rudders. Use a wood block or whatever is hard that will give you evenness if you want. I use my fingers because it gives it a kind of natural roundness and you can feel the finish (there is a technique to it) Finish it with the highest grit you can find horizontally, the way the water runs. Try not to sand the very trailing edge of the foil until done and do it very very lightly, just to even it out. you want the trailing edge to be as sharp and thin as class specifications. Polish the whole thing and you are done. <br>JC <br><br>
