I just finished re-fitting the powerbox base of one of my carbon fins (Leading Edge) which was a little loose in the box as well as repairing nicks in leading edge and repair matches original finish really well. I used super strength araldite mixed with graphite powder to make up a paste. Sets pretty hard but easy to sand and finish.

(PS graphite powder used by locksmiths as lubricant in locks, I think I got it from auto parts shop, hardware shops may also sell).

Thanks guys great advice . Fixing up an old leading edge fin also. Appreciate the help all. Off to bunnings in the morning!

For small nicks in the leading edge I've used epoxy + Q-cell powder, the powder turns it into a shapable paste. I've tried chopped fibres as well but they make the whole thing really unwieldy to gloop into the right shape. I think that any powder would work OK, people have said that baby powder works as well.

For a bigger repair fibres are the go but if you're just after a couple of mm then just powder seems to work quite well.

Yes baby powder(talc) works just fine....

... and graphite makes your fin fast


I commonly use a kneed it stick just because its convenient. It sets as hard as buggery so you have to sand it as soon as it goes off and that's not long, maybe 10 min. It sets as a light grey colour so maybe not what you want.
