I have put a matte black vinyl overlay on my front bumper to black out the middle bar. not only did it take 3 hours with 2 people, but in the Florida heat it shrank a goon inch from either side and now the edges are uneven. i don't want to go though another wasted day of applying and reapplying the vinyl. i have heard of plasti dip but am uneasy about just spraying it on the car. anyone done this before and ave any suggestions.
