Anyone got any idea on the best solvent or similar to use to remove wax residue from an epoxy board in prep for repairing a gin gash on the deck?

Have heard of lighter fluid, but on epoxy?

Handful of foam dust or flour if you don't have access to foam dust just chuck it on and rub it round will show up and take off every tiny bit of wax, follow up with a light sand.

Better than any liquid/chemical and safer especially if you have exposed EPS blank as lots of chemicals will dissolve/eat into it.

For further reference and common sense.

Leave it in the sun and scrape old wax off with a wax comb then fininsh with paper towel. Leaves a thin residue that helps new wax adhere when you want to re-wax it.

Or, same technique and to remove the thin film of wax that's left completely, use that orange oil spray you get in the supermarket- I think it uses a thin mixture of citric acid or something like that. Then fisnish again with a paper towel.

(also, good for removing the old wax residue from a snowboard).

A final dewax wipe down with metho or vinegar [acetic acid] which shouldn't hurt the polystyrene.

Cheers guys, used Indos flour trick and it work a treat. It was pretty depressing to find what was under the wax. Cracks, shatters in a number of places as well as the fin gash and compression dents as well. Considering the board is a week old, four surfs old in fact, and mellow surfs at that, I'm really dissapointed in the large amount of coin I just dished out.

After a rally bash i had yesterday with a two week old firewire and a decent banksy in the back flying around im surprised they survived with no dings :) Also in the back was one of those mini gas stoves and gas bottles making a bit of noise hehe. Stupidity but no damage :)

@Salt what sorta stick is it?

@GS I have a firewire (insert support your local shaper rant) and its durable as! I've givin it a hell of a flogging, kooking my rock entries and surfing stupid ledges, not even the slightest ding! they truly are made to last.

ACB its a Hayden Shapes, Hypto. Yes i fell for the hype, the marketing the whole lot. Haven't worked out if I truly dig it yet. The first few surfs have been promising. Paddles like a dream, Catches waves real easy. need to get it out in a bit more sucky stuff. I seem to be screwing my bottom turn on slow waves also bogging the rail heaps, might just me being a kook but in a stiff offshore like we have had down here lately, I felt like I was getting blown off the back of the wave. I reckon I'll get used to it, once its back in the water.

Not alone there Salt, I trialled the Shred Sled and found it went well in punchy, suck, powerful waves, but when you had to generate your own speed and on fuller fatter waves, it was no good. Might of need a size up though and a touch more volume.

Had a lot better boards than the Shred Sled etc. New Love Buzz looks nice, trialled a 5'10'' the other week, but had too much rail and volume. Gonna try a more refined version when it's available.

Shred sled I've had for a handful of years has been one of the better boards I've had. Not sold on the hyptos though. Just spent two months surfing through south america on a shred sled king, great one board travel quiver...

Salt - if you are trying to de-wax the whole board just clean the wax off with a scraper after 5 minutes in the sun, then damp a rag with mineral turps. Works a treat & gives a nice little sheen. Use it all the time. DON'T GET ANY TURPS IN CONTACT WITH FOAM AT ALL
The epoxy is quite inert but the foam is not. If its just removing the wax around the hole then again 5 minutes in the sun wipe it off with a dry rag then sand the residue off where you need to repair. You can also very carefully use a rag very lightly damped with turps with extreme care not to let any dribble into the foam, just to remove the wax residue as alternative to sanding. You wiil need an epoxy repair kit though not polyester resin.

happy hunting.

+1 for the pickle (you have to scrape the majority of the wax off with a wax comb first and then with a little bit of elbow grease the pickle leaves your board spotless), or you can fill a stocking with flour and tie off the end so its about the size of off a potato, does a similar job but doesn't work nearly as effectively, or if you don't mind a mess after removing excess wax with a comb/spatula etc just sprinkle flour on your board and rub off with a towel, repeat until all wax removed (slightly messier and more time consuming method than the previous 2)

WD 40 spray on and leave for a few minutes and wipe off but avoid and dings open to the foam obviously.

Thanks for the info fellas. I got excited and removed the wax off a few other boards that have not been ridden for ages (years in fact), they have a few dings and I thought I might as well touch them all up while I'm at it. It is amazing what you find under a good thick coating of wax!
