3MScotch-Weld Epoxy Adhesive DP420, Black, Two-Part Epoxy Structural Adhesive, High Impact and Fatigue Resistant, Maintains Bond Strength, 50 mL (1.69 fl oz) Duo-Pak

I bought this to repair a carbon fiber spoiler with an aluminum hardware insert that had been damaged in a hit-and-run. After cleaning and preparing the carbon and aluminum I flooded the gaps with this epoxy and let it set up overnight. Seems to be working perfectly, you can't even tell the spoiler was hit except for the scuffs on the side. and so it does exactly what it promises.

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 There are vendors out there who shamelessly sell out of date product.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 Out of date product may not work as well.Adding: 5/24 I received another tube today.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?

Creates a strong bond I used it to mount some carbon fiber trim on the car it's held up for a couple winters nicelysome good videos on YouTube help you figure out which product to use

This is the best overall adhesive though the website picture shows DP420NS which is the Non-Sag formula. I received DP420 which is totally different so make sure this is the right adhesive for your application.

Great epoxy. Always buy it. The best one

great bond!

Bought this expensive adhesive to adhere metal to a plastic. Description says it will do this. I can attest to this: It will not adhere metal to plastic! After curing for a few days, I simply grabbed the metal ( 3/4" wide x 1" long flat bar), it pried easily from the plastic. All was cleaned and applied exactly as the instructions say.

Bought and used before. Excellent product.
