I've used it a lot over the years. Needs a scuffed surface. I sand with a air tool with 80 grit on new metal and it sticks like glue. They make a top coat for areas that are exposed to sunlight. When doing my rust repairs I also sand blast or sand the pieces that I won't have access later to paint later before I install them. Like the inside of the rocker panel ECT. When spot welding around painted areas I puts off an awful smoke/odor. I keep a fan running behind me so I don't breath it. But I also have to be careful I don't blow my argon gas away either.
