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.

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.

3m consistently makes really good products. This epoxy is the best I've ever used. I've used it for about 16 years in my business. Having black is helpful, but the quality is great. TIP: Read the product application data. Good surface prep is important. Warm the repair it to 120F and hold it there. This speeds the cure rate, and drops the time need to cure to full strength from 24 hrs down to about an hour, and it's stronger too. When buying, check the manufacturing date and shelf life. There are vendors out there who shamelessly sell out of date product. (not with this order!) Out of date product may not work as well. Adding: 5/24 I received another tube today. The seller put their in stock label over the bottom of the product label, covering the date code etc. which is printed on the 3M label when the epoxy is made. Their label adhesive lifted the obliterated the date code when I tried to remove it. What's dumb is that they put the epoxy in a poly Ziplock bag before mailing it. Why didn't they put their stock label on the bag?

Use With 3D Objects Toughened for impact Resistance.

This is exceptional adhesive but why do you pay for it. Almost 50 bucks.
