    ding repair help

    I've repaired dings before using suncure and sanding it down, it sealed the ding for a while, but then it eventually starting taking in water again, and the next ding i ended up taking to a shop to fix and was charged like $125 total for fixing 3 dings, which i thought was a big time rip off...so now i want to do it myself and make sure i do it right, i've been watching short clips on youtube and i have a better idea now on how to do it. I got a big kit and will start repairs soon, but i have some questions. I have 2 boards that I need to repair, one is a epoxy board, which i never repaired before, and the repair is on the deck close to the rail and the other is on the bottom of a poly board and its pretty big, by heel hit the bottom of it during a bad wipe out. Both dings are pretty messy, meaning its not just a fill, there are cracks coming out. Should I cut around the cracks to make one uniform section to fill and patch? or should i just fill the cracks....i was hesitant in doing this cause thats what i did last time with the suncure and it started taking water after 6 months. I have a full kit now with the resin mix and everything. so just need some advice

    Generally speaking, yes, you would cut out the cracks and repair the whole area. It gets a bit tricky depending on how big and exactly where the ding is. A picture would help me answer this better.

    You need to cut out the entire bad part. Cut the glass at the edge of the ding and remove the glass within the ding and any that is delaminated around the edge. Make sure the foam is dry. Fill with a mix of resin, and Q cell. Don't use more harderner then is neccesary especially if the area to fill is more than 1/4" deep. Sand smooth, then laminate a piece of cloth which overlaps the repair about 2 inches on all sides. Sand lightly and sand the edges smooth, brush on a coat of resin, then wet sand smooth with 220 grit, then 400 then 600. With the right amount of Q-cell you will have an almost perfect match.

    When sanding be careful not to sand thru the original or new glass and try to keep the area flat by not using concentrated pressure in one area. I use a sanding sponge behind the sand paper which works very well. Also, to get a good bond, you need to sand the area that the repair will contact the original glass with med. grit. Proper glass laminating is very important on rail dings, especially when they are in the center third of the board, as that type of ding can weaken the board a lot.

    This method is for PU boards. For epoxy boards, you will need to use epoxy and the proper foam dust or you will have a real mess on your hands. Good luck!!

    the bottom pix looks like a tuflite or some other kind of pop out board. You can't use polyester resin on that one. If you buy epoxy resin, you can repair both of the boards pictures with that (it also bonds to poly resin and doesn't affect poly foam). As far as fixing, the advice above is right.

    How do you cut the fiberglass out? Like in ding where there's no physical cracks but there's obvious damage to the glass, like the guys poly board photo above except a little less severe.
