How to Paint a Metal Bumperby William Zane
If not properly cared for, over time metal car and truck bumpers can get rusty and dingy looking. Painting a metal bumper on a car is a quick and easy way to improve the appearance of the vehicle's exterior and takes a minimum of supplies and expertise.
If the bumper is still mounted to the car, remove it to make the painting process easier.
Strip existing paint from the bumper with paint stripper. Apply the stripper and allow it to soak into the paint for 10 to 15 minutes. Scrape the paint off with a plastic scraper. Repeat until all of the paint is removed.
Scuff the bumper with 220-grit sandpaper.
Wipe the bumper thoroughly with mineral spirits and a clean, lint free rag. Repeat until the surfaces are entirely clean. This is a crucial, as a clean surface will ensure that the paint adheres.
Spray on a light coat of primer. Let the primer dry for a minute or so and then apply three to four coats.
Wet-sand the bumper with 220-grit sandpaper. Wipe the bumper with mineral spirits until is clean again.
Spray on a light coat of paint. Let the paint dry for a minute or so and then apply three to four coats.
Wet sand with 220-grit, 400-grit and 800-grit sandpaper. If a smoother finish is desired, you can also use 1500-grit and 2000-grit wet sandpaper.
Refit the bumper to the car if it was removed.
