after a nice session on my twin tip (2010 slingshot misfit) the weekend, noticed a 10cm delamination on the middle of my rail, which needs to be fixed.

now, i have heaps of expererience fixing surfboards, but none with kiteboards. I shpuld be able to do the job but dont know what to use. is polyester resin ok? or should i use epoxy? what happens if you use poly when you should have used epoxy?

I had a look at the slingshot website to find out what they are mad of, but the best i got was that it was made out of 'resin x'

Also, anyone got any tips of what to do if the foam on your bar starts flaking off? I was thinking some kind of waterproof grip tape, but dont know what.

Cheers

To spikey is the foam grip just coming away or falling apart,if its coming away from the bar dry it clean it then use contact adhesive, apply to bar and foam and when it gets tacky push together I've just fixed an 09 bar and its holding up, if its totally stuffed I've seen replacement grips on eBay UK kitesurfing category

Hi Steve, lets say all modern twin tips are made using epoxy, its a lot tougher and gives manufacturers a better control of the process. all the layers were put in a press at 30 ton pressure and then the mold was heated up.

So you will want to replicate that process as far as you can, which means , for you, clean the area you want to stick back together and apply some epoxy, then put a clamp on the board to put the pressure on.

Should work out OK just tape off any area you dont want smotherd in resin after your done.

Ill be repairing two epoxy surfboards this week and you wont be needing more than a spoon full of resin for your fix, so im OK if you want to come by while im mixing my batch.

The grip on your bar is usually the same stuff as the material used for surfboard deck pads

How deep is delamination? I would strongly suggest to use a vacuum pump and bag.

Maybe even an epoxy infusion to avoid dry spots.

Poly and epoxy do not work well together...

Thanks for the advice.

Bar is in pretty good nick, will try the contact adhesive and restick.

Definitely sounds like I need to use epoxy, sq will pm you and see if I am around when you are fixing stuff.

Delam is only about 1cm deep off the rail, just long.

If you need to re tape your bar the best Ive found is the tape you get in bike shops for handle bars. Sticks well & nice grip too.

I'd be contacting Slingshot and having a nice long whinge. Not good enough for a two year old board
My Underground FLX is lining up for its 8th season and is suffering from faded graphics.
Flick em an email and let us all know how they look after you.
