    Good looks man. I always made the mistake of doing wet 400 and thinking that was all I needed to complete the fix. It was always water tight but a part of me wanted that nice polished look. Gonna do this the next time I do a fix.

    By the way the sealer used is Behr acrylic concrete sealer. No need to buy re labeled sealer. You can get it at the local Home Depot.

    For a cheap imitation of super fine grit sandpaper, use the corrugated part of cardboard. Peel back one half of the cardboard and use the "guts".

    Am I a weirdo here or what? I wouldn't even bother worrying about all the super fine wet sanding or the compound stuff. I would repair it solid, and to do so I would use some glass, and then sand it with whatever the finest paper I have is and call it a day. It's a small ding, even with an "adequate dry sand it's not going to stand out much. Certainly won't make a difference in performance either, as long as it's water tight and holds.

    I agree with you in some aspects. I have a couple of old boards that I repaired and didn't try and go nuts fixing. But I can understand if you have a newer board and want to keep the polish flush with the rest of the board. I guess it just depends on the situation you have at hand.

    If its a sanded finish board end with 400 grit wet sand or something that matches what the mfg used, if its glossy work your way up to 1200 wetsand. you can get the right paper at wet marine or a boat store. I repair fiberglass for a living.

    By the looks of the ply stringer it may be a high dollar machine cut PU California performance shortboard so that makes it soft enough to count rides through deck dents. If it is newish then I would grind out the dings and fix them right. If she has 100,000 miles on her (1 good season on a light weight PU board you like and ride a lot) and the deck is mashed down and concave under your feet pretty well then goober it up with suncure and ride on. If it is a Ron Jon china cue then why fix it at all? They ride better with dings. IMHO.

    It was a pretty hard hit. One of those bruises that feels like it's part of the bone. About 3 inches toward my wrist from my elbow.

    Careful of that sealer Mitchel, the surf industry did experiment with silicone sealers in the late 90 s fyi . The problem was repairing em was a nightmare , glass had a problem bonding . Sanding the dings ended up flaking the glass off regardless of a prep .

    @Mitchell probably used the whole bottle by now. A lot of dings can happen in 7 years hah.

    The sealer I posted is what I've been using a long time. No issues with repairs. Its not silicone. Its acrylic.
