70 chevelle ss rear bumper question

[RamAirDave]

Ive only done one of those in the last few years.

Memory is saying we used 3M Weatherstrip Adhesive, since its good for rubber to metal bonding. Masked off the area that the pad was to be, and sanded/scuffed the bumper very well. Have to clamp and weigh the pad down very well while it cures, especially in the curved areas of the bumper.

I know that it held well for two years, but havent seen or heard of the car since, so I cant speak for long term.
