Better to work on it with bumper off or on jacks.
Tape quality is a big deal. I heat up my tape and use a starting agent or whatever that's called.
One L bracket is enough but had two before I tore my first one on a curb.
Test fit multiple times.
You may have to double layer in some areas depending on your lip.
Put a pc of aluminum sheet to protect it from scraping.
Get help if you need someone to lift into place. Hard to take off once you set in place.
I don't recommend screwing or riveting your fronts. Ok to screw on the sides where it mounts on the fender.

Good luck.
