3M Impact Resistant Structural Adhesive, 07333

Bonds great. This product allows you plenty of work time after application. Great for besdsides and doorskins.

Nice product. Dries super hard and grindable/sandable. Made my old sloppy joints on my 66 Mustang look much cleaner after replacement of firewall and cowl. I used this in conjunction with welding but it makes a wonderful joint sealer after the panels are welded up even if not used between the panels. It says to only use resistance (spot) welding, but I used plug welding and avoided the area of weld holes with the adhesive because it does burn a bit and liquifies if it gets too hot. Clamp or screw the panels all around to get them flush then weld. I think it's stronger than just welds. You can see similar products in comparison with spot welding on youtube. It has incredible holding power. I just wish it cost less. For my firewall and cowl I needed a little more than one tube, so what remains will be used on the floor pans. You can use it pretty sparingly (a thin bead) if welding along with the adhesive, and don't try to mig weld through this stuff as it splatters and makes for a poor weld.

Great project. Prep as directed and the bond and finished product come out amazing.

I patched some minor sub frame rust on my 1954 Belair. I cut new replace metal and clean the surfaces used the adhesive as to the instructions. Its been a few weeks driving the vehicle almost every day and so far so good. No breakdown of the metal patches or the adhesive.

great product

This is the stuff I used to replace my rotted floor in my car. Follow directions exactly and your project will come out as strong as if it was welded. Make sure the rotted sections are CUT away and all bare metal surfaces are coated. That will prevent any rust from forming on the metal not in contact with each other. The purchase of Additional nozzles will be needed and a special caulking gun will be needed. When done you can put aside till next time but then another nozzle will be needed. It took me 2 items and 4 nozzles to replace my floor. You could stich weld it after, if you think it will be needed but for me it wasn't necessary. If you don't have a welder or the skills or the money to pay someone else to weld in your floor, then this is the way to go. This product is good for STRUCTUAL repairs. For panel repair there is a cheaper 3M product. Watch it being used on U-Tube

I was in a car accident recently that damaged my fender apron. I was looking into welding a new apron on when I talked to the machinist at work. He said I'd be much better off using rivets. I did my homework and discovered that many auto manufacturers have switched from using weld to using structural adhesive for body repairs. In fact, this is said to be stronger than traditional welds, however it does "peel;" during an impact, so you should use it in conjunction with welds or rivets for more integrity. Obviously, I'm not a pro, so do your homework before you use this, but it worked brilliantly for me. I used this product with stainless structural rivets and it's rock solid!

Used to fix metal roof bows in restoration of classic car. Great final product (set up strong, holds/bonds nicely, & color change state of set-up). Application (prime tube & fill application mixer nozzle) is a bit clunky and wasteful (my only ding).

works great, very strong

Amazing stuff from a good company. Glued on rocker panels on a car with this.

Non retounable donc décevant car ça fonctionne pas ne colle pas
