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

Qcell is your friend here.

Buy a ding repair kit, mix up some qcell and fill that sucker up.

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

yeah Qcell is the go...but I think you may be a bit off with the mix Doggy...I would reverse that mix...70 Qcell 30 resin...think of the Qcell as cement and the resin as water...get enuogh Qcell to fill the hole and then mix the resin in bit by bit until you have the car bog consistency...because that ding has the crack at the very bottom you can chop some glass up fine and add it to your mix and it will hold in there fine as long as you sand the hole well before filling....if you have any bubbles after sanding just paint a liitle finish coat over the repair and fine sand with wet or dry...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

Hey fellas...

What colour does Qcell set? ie does it have a blue-ish tinge to it - or is it pretty clear... as I never hear of you blokes adding white pigment to the mix...

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

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!
