The resin took days to cure at room tempature, but in the end seemed to work well. I tried mixing as instructed by both volume and by weight with similar hardening times of 3-4 days.

Excellent seller and product

This product worked great for my carbon bike frame repair. I made the repair much thicker than I may have needed, because I am very concerned of the strength of the repair. This product arrived in the mail quickly. The resin was slow to cure and needed nearly two days to fully cure; but this gave me a lot of working time with wrapping the layers of carbon weave and with removal of trapped air bubbles. I suggest using very sharp scissors to cut the carbon weave thats wetted with the resin on pattern marked parchment paper; or else it will fray apart on you. I practiced on a broken carbon fishing pole before doing my bike. The bond strength and repair strength was excellent on my fishing pole test piece. The bike frame repair is holding up well so far with 300 miles of rough LA roads and my 230 lbs weight.

It hardened completely unlike other resin mix I have tried which never harden properly

I just used this product to fix a crack on my carbon rear triangle seat tube and it worked as specified. You will have to wet sand the final product to get a nice smooth finish.

I have repaired fiberglass and carbon surf/sup boards for decades in this repair on a very high end sup. The carbon sheet is almost impossible to cut and place without it unwavering and the epoxy will not set at all. I added some microballons on the second coat but nothing. It’s like they sent wax instead of hardener Neither is labeled How to even clean this up and start over. Ahhhhh. This product is terrible

With the help of YouTube videos, it’s fairly easy to use and apply. Generous amount of carbon fiber, enough for at least 2 repairs. I fixed a crack on the top tube of a bike, let it cure 48 hrs, then sanded down. It looks good, waiting to be painted.

I didn’t receive the carbon fiber fabric, just the epoxy.

This kit would probably be fine to cover an object for esthetics, but it is not a structural kit by any means. The epoxy is useless and provides no rigidity. The carbon fiber has tape on all the edges which becomes waste. The carbon fiber contains no binders and it’s impossible to work with, and is a pain to cut to size.

If you are new to working with carbon fiber, here are a few things I’ve learned! This was my first time so I’m sure these are obvious to people who have worked with this material before. First the instruction don’t say it, but remove the yellow string. When you apply the epoxy you want to feather the fiber out as much as possible. Keeping the string on will create weird edges. Apply with a paints brush on small areas at a time, pressing firmly down to make sure the fiber is against the actual surface and not hovering in epoxy. I would try to buy some type of clear film so that you can smooth the surface down while it’s curing. I didn’t and just have a lot of sanding to do, but if you used like cling wrap with painters tape I think you could get a better result! Mark of your area, with the tape, apply the carbon and epoxy, then clickers film over that and smoothhhhh out. It feels strong on my surfboard! We will see!
