It’s not a total beater, but a possible track car, so I tabled the pop rivet idea and wanted to go with a permanent but hidden system.
For now, I used #6 st st machine screws with washers and nuts. There just isn’t a lot of meat on the bumper cover lip to work with.
Are you guys talking about the two part JB Weld epoxy or the old standby black and white mix.
For extra adhesion, I was going to drill small holes in the aluminum.
