    Usually have all my dings repaired professionally but this is so small, waiting a week and paying for it seems like a waste. So I'm using sun cure for the first time. It's the very tip of a diamond tail, so I want to sand it right. Which flavor sandy p should I use? I picked up 220-320-400 grit. Thanks in advance for the help yo's...

    Usually 150 for most of the grunt work and a 220 for most finishing (gloss aside of course.) Hitting with a 400 will never really hurt afterwards though. Pro's use speed spray, or something like it when its complete which magically blends it with the boards finish and removes all those really tiny scuffs. You need a decently heavy grit to rough it up first though so the stuff will actually stick, like a 40 or 80.

    This stuff works great, wipes on with a sponge and sets up shiny and hard in about 10 minutes. masks the sandpaper scratches and kind of seals things up a bit. An $8 pint lasts years of ding repairs and glassing a board or two a year.

    You dont have to buy some magic potion to get the scuff marks gone. Just get that 400 grit wet and sand away. Its called wet sanding.

    Yeah its more of a sealer than something cosmetic.

    No way, for a white board repair that small...just hot coat it properly and like everyone else said, sand it out fine, and wet sand it if you want it to pop.

    I ride everything bro. I've got firewires too.. every one of them has been dinged also. I have a spitfire in fst that whacked my arm a couple weeks ago and has a crack on the rail... I'm getting that one professionally done though. This just seems like it should be a simple thing to do..

    Mr 3rd,

    After you wetsand with the paper you got- pick up some 600 grit to clean it up nice. To really finish it off- pick up some 3m rubbing compound from your local advanced auto.

    Oh yes- almost forgot , return the sun cure and get some reg resin with catalyst. That sun cure stuff is ng , it will be harder with that ding you got too

    If you want to repair the board properly, then yeah, dropping a glob of sun cure and sanding it is a bad idea. Youll be fixing it again within 5 sessions, (because exactly like the guy above said it will be chipping out) and water will probably have gotten in, so youll be worse off than where you are now.

    sand, glass, sand, hotcoat, sand, sand. Its really the only way to fix it properly.

    or drop it off at my shaper..haha. Thanks for all the input, but it definitely seems to be more of an issue than I thought. I know nothing about glassing or hot coating, or even sun cure for that matter..

    Its really not hard. I'm not the best at repairs, they don't always look pretty. But they keep the board water tight. An hour of research is all you need and you should have the know how to fix that ding.

    Edit- plus it's just a good thing to know how to do if you surf alot. Why not learn now

    Yea give it a shot- it's not a hard repair. And remember sanding is the most important part.

    For your repair:
    Mask off area with masking tape
    Lightly sand the area with 80 to scuff up the area good so the resin will stick
    Mix your resin (not suncure. Save the sun cure for surf trips and emergency)
    Work quickly with resin.
    Take old or cheap paint brush and paint on resin over ding and masked area.
    Let dry until gel- half hour- and gently peel away masking
    If your lazy and don't care- you could leave it like it is now.
    But if not- when dry start sanding
    80 or 120 first- try to Sand (edges mainly) flush. Try not to sand much of the board and center of repair.
    Then sand entire area with 200 wet
    Then 400
    Then 600
    Then rubbing compound to get that gloss look back.
    Then paddle out at Belmar
    Proceed to shred and get barreled.

    are you suggesting that he repair that ding (that looks like it goes all the way to the foam) without any fiberglass? that won't hold up, especially on the nose.

    Yes I am suggesting that. It will work. I use to do ding repair.
