Repairing some hull damage on Superjet?

[Hagan]

Bought a '17 Superjet last year and have damaged the bottom of the ski. Been riding for 12 years and never damaged the bottom of a ski. 1st day out I hit the bottom of the river. Left some small scratches but oh well. About a month later I was camping at a lake and was about to take off in some murky water from camp. I waded out and jumped on the ski and hit a hidden rock. It took a ~1/4"x1.5" chunk out a rib on the bottom. How exactly do I go about repairing this properly? I paid $8500 for this ski and don't want it to look like poop. I'm thinking a color matched paint pen will take care of the small scratches. I've been watching videos of fiberglass repair but I'm uncertain because it's SMC.

Thanks

Only use Epoxy on SMC.
You can buy a small epoxy kit from a fiberglass supplier as well as some Cabisil (thickener).Mix in some chopped fiberglass strands too.This should take care of chunk missing from the bottom.Number of companys that sell these items. U.S Composites,Fiberblast,etc.Probably a supplier somewhere closer to you.

Looks like a paint scratch. Black appliance epoxy rattle can.

Its definitely a chunk taken out. Approx 1/8" deep and ~1" long. I'm planning on selling it that's why I want to fix it.

Honestly I wouldn't bother. It isn't bad enough to make any difference. If you have to fix it I would get the small evercoat gel coat repair kit.

I have used marine grade fairing putty for small fixes like that. It worked rather well with the SMC and sands down similarly too. Then just shoot some appliance epoxy onto it, let it cure and you're good to go. I will get a link to show the fairing putty I've used.

Here ya go...

Fill that with cabosil thickened epoxy or marine Tex etc and feather blend. Repaint the bottom hull with interlux epoxy. That's the right way to do it.

Thanks guys! I ended up trading it in on a new motorcycle. Happy with my decision because I disliked the hull design. Should have kept my trusty old SN. Got burnt out on ski's and just had my first baby. Going to be a couple years until I get back into it. Thinking of building my own ski next time around. Thanks for all the help
