The damage is not that serious but I would like to repair it anyhow....Will ptex stick?? Ptex is not just glue sticks for hot glue guns right??

Sand it smooth and put some resin in the scratches. I personally would not worry about those as it does not go to the fiberglass or the core.

You can try using a clear P-TEX candle. Not sure what Wainman use has base plastic could be PET or maybe UHMWPE (P-Tex, Durasurf) base looks opaque could be UHMWPE. Idea is to clean up area with blade and some Isopropyl alcohol. You light the candle and drip the melted plastic into area building it up. Then just take a plastic scraper and level it out again done.

Video below gives you a basic idea.

And did you fix it? People are kind enough to take time to reply you should maybe do the same.

reviving old thread. Just confirming best thing to do.
I have deep scratch on my carbon board (fone Trax) from reef and rocks (Caribbean and low tide local spot)
Didn't go to the core, only in first (plastic) layer?

I was thinking to use razor blade to smooth the bits that stick out and maybe lightly sand it.
Would you use sand paper or steel wool?
Is there a particular brand of resin to add and sand?


What about corners and rail of board, there are a few nicks with HDR plastic busted. some form travelling, going through cancun was the worse of it ;(
Thinking of just smoothing it with razor and putting glue or resin to make it water tight.

The purpose of sanding is to rough up surface for better mechanical grip. use sandpaper not wool. epoxy grips better than ptex I would use that. ptex is great for quick fixes but there's so much it just doesn't grip to. if you ptex try just a small section to see if it holds.
