i painted my side skirts and they look pretty good, not as shiny as the rest but a few more layers of clearcoat could fix that..

the bumpers are a little bigger tho and its gonna be harder to make the paint even. you might want to buy something to spray the paint better than just using the can.

first you want to sand the old paint off thoroughly using different grit sandpaper. start with course first and then go finer. dry sand then wet sand with every grit of sandpaper you use. once all the paint is off you can start using 400 and 600 grit sandpaper to make it smooth.

I got my paint at autozone. you can find almost any color there just type in your color code. basically you need primer, the color spray, and clearcoat. first apply a layer of primer, be careful not to let it run. then wait 10-20 minutes for it to dry and then dry and wet sand it with 200 or 300 grit sandpaper. Then apply 1-2 more coats of primer dry and wet sanding inbetween coats until its all evenly covered and you cant see the plastic underneath.

Then dry and wet sand the primer and let dry then apply the colored paint just like the primer in thin even layers. dry and wet sand in between with 400 then 600 grit sandpaper. you may want to do about 3-6 coats of paint so buy alot if u want it to look good. on the last paint layer dry and wet sand with 400 and 600 until its very smooth.

Then let dry and apply 2-5 coats of clearcoat depending on how shiny/dull you want it to be. the more coats=the shinier the paint will be. in between clearcoats, dry and wet sand lightly with 600 (or the finest sandpaper you can find) on the last clearcoat sand with the finest sandpaper you have until its smooth. then let dry overnight and it should be done.
