Yes you can. You will need a special paint for the bumper that has a flexing agent in it or it will crack the first day it gets too hot or too cold. You must also prep the bumper or the paint will not stick properly. I suggest you find and automotive paint supplier in your area. They can mix the right color with the flexing agent, put it in the can and also direct you to the proper products to prep the bumper and some pointers too.I want to spray paint my plastic bumpers?
you will need to use a grey scotch brite and some pre-prep cleaner first to get it keyed up.Then you will need to apply a clear plastic adhesion promoter to help the paint stick.The best colour primer to use would be a mid grey.You should'nt need to use a flexible additive unless the plastic is soft and spongey but the choice is yours,just bear in mind it will slow down the drying time of the paint. Good Luck
Yes its possible to paint the plastic bumpers on your car, however one word of caution. Some manufacturers use a textured surface on the plastics, this surface can be a real pain to flatten before painting. As the other contributors have said you need to use a gray plastic primer rated for hot and cold weather. Try Halfords for you pre-mixed paint. Another suggestion would be to try eBay to see if there are any colour coded bumpers for sale.


Ja.
first clean the surface with a grease and oil remover then use a 1500 grit sand paper to rough up the surface then use a flexible primer DuPont makes a good one auto parts stores such as Oreilly and parts plus caries them the primer color should be light grey then when it is dried use a 2000 or 2500 grit sand paper to smooth it out repeat until acceptable then DuPont makes a flex paint that will go on nicely also don't forget a clear sealer and note that all sand paper should be wet to assist in removing excess grit and debris that are left behind last when all is done and set build with a good polish and wax to bring out shine and provide added protection
