DIY - Fixing Carbon Fiber - Crack Repair 

Any local hardware or auto paint supply store should have a clear epoxy

Makes sense

If there was uv specific clear. The resin choice should be one that says it's uv blocking. Clear coat is not gonna stick forever

You have the Internet. Amazon always shows " other people bought these too" I'm sure you can find all of it there

This isn’t a structural piece and the crack was just on the top layer of resin, Heat won’t improve strength unless the resin you use requires a specific heat range to achieve correct cure time. If you wanted to get a stronger bond for something structural ideally you would want to draw the resin through the fiber with vacuum or push the resin through with some kind of injection method and or what most people do is just add more layers on the back side to to spread load.

@@jumpgarage Thanks. What brand of epoxy resin do you use (and series in that brand)? I hope someone has made a video on a small DIY autoclave (a vacuum chamber-"pressure cooker" combo) using a household pressure cooker :-)

Nope. Perhaps fiberglass resin is. Watch vids of people doing large bar tops

It appears to be 5 minute epoxy, which is not a good epoxy to use. You can see it went on yellow, and since it has no UV inhibitors built in, it will crack and yellow in the sun. The best product to use would be a 2K (2 part) clear coat. Either spray it in a cup and use a tiny paint applicator, or use the paper squeegee method, building up the layers of clear until it sits above the surface. Then block sand and polish.

You could. I recommend a marine outboard brand clear in a spray can. It's the best out there. Really though people don't clear coat fiberglass, so I would just focus on surface treatment like wax or ceramic

You right, do as I say not as I do :)
