Thanks for the great video, which is helpful for me. There are a number of different epoxy’s available on the market. Which product would you recommend?
The product I use is produced by a new Zealand company called Adhesive Technologies NZ Ltd. It is a structural adhesive epoxy resin. 4to 1 mix. Brilliant for repairing scratches. Owner of the company is legend Grant Beck.
Hi, Yes, I would wet sand with large sanding blocks. I would avoid creating knife edges as is dangerous. Some foils have large decals which create separation if there are fixed to the outer boundary layer. Super important that the leading and trailing edges are as true and as smooth as you can get them. 800grit gives a good finish. I may look at this on another video. Every foil is different and when you first start to dress one up , it's like prospecting, you never know what you're going to find.
Hi I have a question about the trailing edge of carbon hydrofoil masts. I've noticed on my 2016 lift and now on my 2021 Slingshot Phantasm that over time small Knicks and chips develop. I protect my gear with a padded mast cover all the time and I haven't damaged them at all. Is this a thing you are aware of? Do you have a clip on how to sand/fill/ repair. Cheers Grant
Hi Grant, This is an interesting question as like you all of us in the NZ class buy covers and protect our foils as best we can. I'll poss a theory that foils that are well used develop ware on the leading edge from water friction. So in effect the boundary finished fro the factory has been worn off. Sort of like the rocks in a fast flowing river. Once gone you can observe small pitting as the fibre weave is exposed. Best remedy is to fine wet sand and spay a coat of DuraPox. Then finish with a wet sand to reestablish a smooth boundary layer. Hope this helps.
Informative video, thanks. I hadn’t thought about using packing tape to keep the shape of the resin added to a void. What do you do with little nicks on a leading or trailing edge? Same technique no matter how small? Would you ever smooth out nicks with sandpaper, which would also slightly change the leading profile?
@@shmish Hi Doug, Have a look at the video called Perfecting the Boundary Layer. I think I covered some of your questions. Key thing is to be carful not to change the foil profile by sanding out deep scratches. There is only so much you can re-fair before you need to prep and fill. Hope this helps.
Thanks for the nice videos, could you do another video showing how to repair a bigger damage on the tips of the wing if small part is missing?

I use a product produced by Adhesive Technologies here in New Zealand.
Thanks very useful. I’ not sure I’ve understood (I speak french) the type of product you’ve used : is it epoxy glue ? Double composant ?

Hi Thierry, It is an epoxy glue
I got my iqfoil mast cracked near the top. Is there any way to send you a picture to know if it's something to be worried about? Thanks!
Gary, do you give your mast the same treatment as your foils, ie fairing the foil & thinning the trailing edge to 0.5mm?

I find I get chips in the mast from hitting small sticks and seaweed (with attached stones). It's sadly part of the game
good vid Gary! is the graphite powder solely to colour the epoxy black or is it used as a thickening agent?
Colour only Tim
It’s a very fine powder or dust.
