How To Repair Carbon Fiber Cracks

In this video I show you guys how to repair carbon fiber cracks with nothing more than sandpaper, resin, polish and elbow grease!

Fixing your broken carbon fiber parts can be time consuming but it is economically worth it since carbon fiber parts are very expensive!

Remember not to sand the exposed carbon fiber cloth if you can avoid it! Disturbing the weave will make your repair obvious. If the cloth has been cracked through, you can still salvage your part if you do not care about how it looks. Reinforce the back side with a new piece of cloth and soak it in resin. Use chopped carbon fiber on the front and build up the area until there is no longer a void. Sand smooth and polish for a nice finish!

Very good procedural tutorial on how to repair carbon fiber. No need to allow shops to charge huge repair fees as long as you're willing to be resourceful.

3 years later and this video is still useful. I bought a really bad condition CF hood for my g35. I got it for 100$ had some deep cracks on both sides as well as the front. I sanded, filled with resin 3 coats. One one side the cracks are completely gone. On the other side they are still visible BUT it has a layer of resin so you can’t feel it, imma wrap it and leave the vents visible. Thank you very much for the video 🔥

Dude, thank you. I cracked my Seibon hood last week and they don't make them for my car anymore. This was a super informative video, even 2 years later. Subbed'

Excellent procedure for repairing carbon fiber cracks, I used this fix to repair golf club driver head carbon fiber crown bad crack. It works well after repair. I used J-B ClearWeld.

This video is a live saver! Thank you for being so thorough with the explanation hopefully I can fix that chip in my trunk !

My drum pad is cracked and this guy basically fixed it for me. Thx

Thanks for the vid. Hubby took his Triumph MC in for a tire replacement and they must have backed the bike into something solid and made a triangular, dime sized, full thickness crack in his lower graphite fiber can cap. Guys take a photo of everything. The cans were optional Triumph accessory (made in Italy) for $1200. Replacement parts difficult to get.

Great stuff. Thank you. I truly appreciate you including alot of the necessary information that people often exclude.

I just bought a 911 with all carbon fiber interior trim. Almost every piece is cracked. My plan was to replace everything over time, but I could probably buy another Porsche for the cost of that. I think I'll try you methods on the most inconspicuous piece/spot to test my skills and see how it looks and then go from there. Thank you for the video

[davidknechtel]

Exactly what I needed, Thank you for this!

[sluggomagoo]

Nice that you explain all your mishaps.

Mixing the catalyst and the resin too quickly will also make bubbles. Mix it a bit more slowly instead of whipping it up ;)

[neilbutler-wasabirc]

Thanks for a great video. I have a carbon spinner on a RC plane that got scratched in a crash. This is going to help a lot to solve the problem and get the spinner back to looking good.

To prevent bubbles use MEK, blow with air and pay attention to your resin that nothing goes in during combination nor dirt on the part where you are using resin.
Some dust can create air bubbles and that's why it comes out like that, while polishing with resin also your brush should be new and clean, alway use air blowing and after MEK.

Great video. I have a carbon hood on my car thats cracked and you can't find a replacement in the exact same style or any other hood that looks good so this is gonna help me out tremendously.

[mustangmach]

Great video I’m happy you took the time to show the steps thank you

[ld_ryan_u]

Ordered a carbon body panel for my project car. Shipping company absolutely destroyed the box and scratched/cracked it (MTS Freight). I, now, plan on painting over it so it doesn't need to look perfect. Going to try this and see what happens!

[jg_media]

Thanks for this! Just what I needed to give this a go myself

[brosec]

Wow, thanks for the tips. I am looking to repair the front spoiler on my XKRS, I will definitely be taking my time on it. Good video 👍
