I also think that this is totally excessive. Bumpers do not rust like the hood (chips).
Replacing that bumper most likely costs only a little more than this application.
This doesn't protect from reasonable curb/crash damage. Reapplication required.
ONLY very slight scratch. Also reapplication required (aka very expensive scratch).
But I'm ready to live with a small scratch on the bumper rather than waste money.
I'd better waste money on ceramic wax annually.
