I guess a video of me flexing my bumper where it was full of small cracks is in order!
I have used PPG and I love the stuff, But the 3m/SPI combo is fast and works. You have to blast the epoxy off the rubber or dig it off with a knife is sticks so well.
SPI has been use for Endura Bumpers for over 15 years successfully .
The 3m Adhesion kit was not developed for rubber, but I do like it and have used it.
99.9 of all Bumper covers do need Adhesion kits/promoters, and are NOT rubber.
