Review: Very high-quality epoxy. - Folks, just ensure you are using the right epoxy for the job. In my case, I needed to fill in a non-load bearing structural gap in a piece of carbon fiber that was created when it was penetrated by a screw. For this purpose, this epoxy has been excellent, it has created an sufficient bond, and I speculate it is actually stronger than the surrounding structure. I highly recommend this product for your epoxy needs assuming the application is appropriate.
Review: Superior adhesive - I was on fence due to expensive tag. But this turns to be a very high quality adhesive. You can't use it for big projects since its expensive as Gold.

### ⭐⭐⭐⭐⭐ Aluminum to carbon fiber bonding
*by T***S on November 4, 2025*

I used this to bond an aluminum insert into a carbon fiber tube that required very high strength. Worked excellent and is still holding after 4 months of daily abuse. Highly recommended if bonding metal to composite. Easy to use after purchasing the dispenser gun and nozzles.
