Had some scratches on my frame and the shop suggested I use epoxy. Wanted to make sure the kind I’m getting isn’t going to fix up the frame though.

I feel like that’s going to be a mess, why not use a UV safe clear coat paint?
All of my bikes, except the newest one, have scratches and chips around the drop outs. I have never worried about it.
I’m not sure about this exact JB Weld product, but in general epoxy needs a clearcoat over it to protect from UV damage.
FWIW I used this exact epoxy with a tiny bit of sanding to even it out and hit it with clear nail polish afterwards on my carbon bike. It’s lasted 4 years and still holding strong
Will eventually haze and/or turn yellow and become brittle with prolonged exposure to sun and sweat.
If it’s a simple and superficial scratch, then use clear nail polish…..
It’s probably fine but this stuff does create heat when mixed, idk if that matters much on carbon, but might melt the clear coat if you haven’t sanded through it. This is however what was recommended when bonding a steerer extension into a carbon steerer so I say try it
That’s glue, am I right?
Ive used super glue on a few guitars with gloss finish. Apply and whittle off dried excess with a razor blade. Might work?
I’ve always just used model paint for touchup, Testors but I haven’t tried it on a carbon frame. On my Campagnolo carbon levers, I’ve used Midwest Aero Gloss with good succuss but that’s discontinued.
I imagine any model paint would be fine. Let cure for a month and then put helicopter tape over the trouble area.
I would not be using an epoxy. With paint you can thin it down, remove it easily if you aren’t happy with the result, build up layers. I don’t know how well this JB Weld product would flow and it has a very short working time. I suspect the repair would look as bad as the damage, just in a different way.
Yeah its safe…. but kinda a pain in the ass. It would be better if youre trying to level and repaint.
I just hit paint chips with a bit of automotive clear coat or nail polish to keep the water out.
