3M 08116 Panel Bonding Adhesive Cartridge - 200 ml

Worked as expected

Cars

I was gluing a new panel on the rear hatch of my Ford Explorer. I read a lot of the reviews and it was difficult to tell whether this would work well with my application. This piece was about 6 inches tall by 4 feet wide and the back was plastic and so I was unsure if the glue would adhere to it. I did sand the surfaces that I would be using the glue on, and the only issue I have with this glue is that there are two versions. One sets up in 20 minutes which was way too short, and the other is this version which takes 4 to 6 hours. And you really need to let it sit for 24 hours. But I will say that once it was all said and done this panel was now part of the car. It’s solid and I don’t think it will ever come off again. I mean it’s like there is no difference between this plastic panel and my car where it’s attached. It’s welded. I did tape the entire area and clamp it. I left it for 24 hours. I’ve been using the rear hatch for a month now. No issues. So obviously the key is to keep it tight and stable till it’s fully cured. So I’d say this was well worth the price.

I use it on stainless steel where nothing else works. I've learned you have to clamp it hard because it needs to be no thicker than the tiny glass beads inside of it. All excess glue must be squeezed out. It sticks to stainless, but not to itself. If it is too thick it is easy to pull apart because it separates where it is trying to adhere to itself where it is thick. When clamps cannot reach the area glued, I pile weight on it, a lot of weight, to squeeze out any excess. And then it holds great.Of course, with stainless steel, the area must be deeply abraded.

I've been using 3m SEM panel bond for about 10 yrs now. In autobody applications I almost prefer it to welding. Extremely strong bonding adhesive. I did an experiment by allowing the product to harden on 2 pieces of joined metal. One caveat is any close by heat generated by my mig welder softened the adhesive so in my opinion either bond your autobody repairs or weld them. Don't mix the processes in any single area of repair. Excellent product.
