surferstu WA 637 Posts	Posted 14/10/2011, 12:23 pm Any thoughts on the best way to fill up a large dent on bottom of surfboard. I dont want to just use resin and add too much weight. What I was thinking was to sand the general area seal the crack with resin then use something like a light weight selleys space filla or similar which can be sanded flat, then finally fibreglass cloth and resin. Any ideas appreciated

Sand it first with 80 grit dry paper, really give it a good sanding! Mix resin and qcell, 70/30 mix 70% resin 30% qcell, mix together with a drop of hardener. It should be like car bog. Sand it down flat so the repair is lower than the rest of the board. Then cut a bit of glass mat to suit and mix some resin to cover the repair. I use a small paint brush to apply the resin to the cloth, dont be afraid to build up the resin and try and keep air bubbles out. Let harden and sand with a sanding block until flat and you are done

Yea I was thinking you wouldnt want it too thick so it lays out flatter. If I was trying to build up I would go for your mix. I did one recently and it came out unreal. I will try and find a pic

Cheers The qcell is white but its not a clean white and it rarely matches the colour of the board. Tbh I dont worry about the colour when fixing shortboards, I just concentrate on getting the finish the same as original. Im sure Ive got pics here of a rail repair, I will look now

PaddlePig WA 289 Posts	Posted 15/10/2011, 10:28 pm One tip from me mate is I wouldn't bother sealing it first, then using Q cell... Just Q cell the bloody thing. I'd rough it up real well. I use the nastiest grit I can find, then lightly hit it criss cross with a stanly blade. Q cell it right up. When I mix my q cell I do it like making pancakes, mix the resin then add some q cell. If it still resembles liquid I add more. If it still is somewhat liquidy I add more and more untill it is kind of globby, instead of runny. Then sand it back and put a coat of cloth then filler resin. Battle wounds are great for boards! They love it!
