Just amazing Stuff
I've used panel bond before for various things and it was the first thing that came to mind for this job........fixing broken headlight mounting tabs. And it freaking worked. Saved a set of aftermarket headlights for one of my vehicles that were picked up on a whim for dirt cheap because they were broken at the tabs. They're now mounted and holding up great. BUY EXTRA NOZZLES if you're going to do a small job like this.

Very grabby and holds tight
This is a very strong adhesive. It is very tacky and grabs immediately. It is difficult to slide the mating sides around once the two sides of adhesive make contact. That's just something you need to be very aware of. But this is very good stuff. I will use it again.

Don't but this one, find another vendor!
If your looking for a replacement for your gun as show, find another place to buy it or you'll get the children's size like I did with no way to return it. $35 down the drain.

Amazing product!
Follow directions and you will never use your might welder for joining panels as this holds just as well (or even better) without burning protective coatings which then allows rust to form. You do need to grind any coatings off from the two adjoining surfaces providing a bare metal roughened surface for a good bite. The panel adhesive forms a waterproof barrier where moisture cannot get to the metal surface. If it does, you are not using the product correctly. I use a few sheet metal screws as needed to hold the panel in place until the epoxy cures. A small amount of adheasive should ooz out along the seam edges ensuring that you have used an adequate amount. Then I grind the heads off and roughened the surface around the seam then apply a good quality waterproof short stran filler. Shape, sand and finish as needed. Been using this product for years now. Had a small quarter panel patch repair to do on a 1995 Toyota. This was just the right amount to do the job.
