I repainted my car last year in my garage.
I used plasti-dip on all of my trim:
-bumper rub strips
-door rub strips
-chrome window trim
-ugly brown windshield gaskets
but I used rustoleum gloss black spray cans on the body.
Having all the plastics the same color, rather than unevenly faded, freshened up the looks of the car a lot. I’m very pleased with it so far. Overall, it’s pretty easy to work with, but it can be slightly annoying at times. Some edges will pull up and start peeling (rather than chipping like normal paint), and there isn’t a good way to blend a repair into that damaged area. It works much better with the trim completely removed than with masking, since removing the masking tends to start the peeling.
I have no experience with painting the sheet metal with plasti-dip. My opinion is that mistakes made in flat/satin finishes are less apparent with bright colors than dark.
