nice product

This product cures well and gives a high gloss finish. Like any carbon fiber it is delicate or susceptible to over manipulation. Therefore for best results lay down the a large section and cut to size while in the mold.

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!

Epoxy never set, even when used according to the directions.

Perfect

The carbon fiber and resin combo made it easy to just mix the resin and apply. The 1:1 mixing ratio didn’t require much thought. The only thing that took a little more care was working with the carbon fiber. Cutting the carbon was easy, but the carbon fibers started to flake of fairly easily until resin was applied. It could be the carbon fiber thickness or my lack of knowledge on how to properly work with carbon fibers.

I used these materials to repair the seat stay on my wifes Trek. The package contains enough carbon fiber for a very large number of small repairs like this plus some 2 part epoxy, probably enough for 4-5 such repairs. I used a two stage process, applying the 1st layer, letting it dry overnight, lightly sanding the first layer, then applying the 2nd layer. A critical success factor is using heat-shrink release tape to compress each layer. This is a must do part of the process. Lay up the wet material and immediately wrap the tape tightly around the repair and shrink the tape with a heat gun on low. (Wrap with the outer side of the tape on the repair, opposite of how you would usually use tape, because the PTFE side is out.) This tightly compresses the material, aiding in mechanical adhesion and creating a relatively smooth surface that only requires light sanding. I found 100 yds of Hi-Shrink Release Coated tape for about $28 delivered. So now I have enough tape and carbon for about 75 more repairs :-) Remains to be seen how the repair will hold up over time and under stress, but for now everything looks great and seems to be strong.

It was delivered on time and what I received as was indicated. The product is weak, carbon fiber is low grade and the resin-hardener. Carbon is very airy, the epoxy at 2 to 1 mix did not form at 70 control degrees for 48 hrs, leaving the project a flimsy useless.

I like it and it is what I ordered, the only thing I don’t like is that tape around the carben sheet. I don’t see it serving any purpose.

I mixed the resin - hardener as instructed one to one- the resin never kicked off - remained tacky - created quite the mess for the piece Im working on not sure how to resolve the issues going to be a nightmare ! Kit is not worth the money I spent on it
