3M Panel Bonding Adhesive 08115, OEM Recommended Two-Part Epoxy, 200 mL Cartridge, Bonds Metal & Composites for Auto Body Panel Repair (1 Cartridge)

This stuff is superb! High grip adhesive. Holds where it is placed so make sure to put it EXACTLY where you need it since you’re not going to get it off again! Adheres to literally everything I’ve tried it on.

great product

I used 3M 08115 for the first time on my 1954 Chevy Pickup that needed some small patches on its holey roof and firewall. I chose this product after many hours of research and debating vs welding, braising, fiberglass, and other products. the le reason why I chose this is because welding large surfaces such as a roof can warp the roof if not done properly and even then there is no guarantee. Another reason is that welding melts both metals down and can potentially inbed impurities and rust into the weld only to pop up later. With this epoxy you eliminate the potentially for any of this to occur. This is probably some of the reasons why most car manufacturers are using this product to secure their panels on their cars in lieu of welding. Also, because it seam seals all in one step. From all the forums posts and reviews that I read I was unable to find anyone that had actually used this product that wasn't completely satisfied with it's performance. I borrowed a really nice gun (it requires a double tube epoxy gun btw) from a friend and went to town. It applies like hot peanut butter, gives you plenty of working time, smooths out flat, and it cures hard as steel. I love it. I have since used it on other projects and it has performed great. Some tips: It says on the product material that you can reuse it by leaving the tip on there, let it dry and leaving it on till you need it again at which time you just unscrew it and put a new one on. I read this after I have cleaned the outlet very well and put the top back on. This can be a little tedious. Using the used tip seems a lot easier to do. Another tip is that I was working with small 2"x 2" patches for my non structural hole repair. I found that using small yet strong magnets to keep the patches in place as they dried worked awesomely. For the intended application, it is the best there is. Try it and you'll agree. Update....... I have used this product a lot since this posting and continue to be in awe of its strength and ease of use. I can see most welding falling into antiquity when everyone finally brakes from what they are used to and tries this stuff. BTW for shorter claiming times, apply heat from a heat gun. It sets up in about three minutes. Another benefit to this product is that you can bond unlike metals such as steel and aluminum and since there is a layer of epoxy in between them you don't have to worry about them reacting with each other causing galvanic corrosion. sorry for the long-winded review but I hope you find this helpful.

Wow!!! This stuff is fantastic. Grips like no other. Goes on easily and cleans up just as easily. It hardens quickly yet has a long enough window that you can work with it after applying. It's not cheap, but if you're doing auto body work, YOU NEED THIS.

Wow. This is serious stuff, and really works. Don't treat it like a toy. Do all your prep work properly. Use the right kind of gun, made for the purpose. And be ready when the stuff comes out; it can be messy. When they say "bonding" they're not kidding. Have yet to see how the bond holds up over time, but so far I'm impressed. AND it got the job done that I needed done.

So I decided to buy this for my windshield welds I welded the pin holds and shaved it down to bare metal. After I did I proceeded to brush this all around my windshield let it sit for a whole day came back and my gosh is it sturdy. I’m yet to put the windshield I’m sure the guys will add primer and then the “glue” and windshield. After doing some reasearch and talking to some body shop guys this is totally safe to do and improvement over paint as paint can chip. Again it’s a whole process that goes into this I read forums and chemical reaction threads and called four shops and visited 3 to make sure! It seems it’s solid and will do the job I like this as water won’t effect this and rust is in the past unless of course like paint I chip it and don’t treat it. Overall gets stiff pretty good coverage is good easy to use with the proper gun of course.

Works well strong just became full mixing it is runny but works great

Love this stuff. I glue almost everything back together with this stuff. I prefer to weld my body panels on, but I panel bond all kinds of things together around the shop and house, and have been for over 20 years.
