Panel-bond is a very strong adhesive that I used to glue roofskins and 1/4s on Fords before I retired from a local Ford dealer Bodyshop. I.E.S. is what I prefer. It is a 2 part epoxy that is acually stronger than welds. I also use it to seal seams. I use a spreader and squeeze it into the pinchwelds. Stuff is awesome. I did my own test on how strong it really is. I bonded 2 pieces of frame scrap and put it between two posts on a frame machine with mo-clamps and pulled 8,000 psi. and the steel at the clamps ripped. Bonded seam was not disturbed.
Remember!!!!!!!
Parts must be submersed in this product! I soaked these parts for 24 hours. It really works. After 12 hrs I pulled the parts out and hit them with a wire brush and returned them into the solution for another 12 hrs and what you seen in the picks is before and after the use.
