so i am picking up some new bumpers tonight and they are dark green and will be going on my black DC

i am thinking of painting the bumpers myself to hold me over for a few months so if anyone can show me exampes of some bumpers they have painted themselfs that would be great, preferably black but doesnt really matter.

or if you cant find a picture any insight would be great, like a process or if i should sand all the paint down first or jsut go ahead and primor over it... any help is appreciated

thanks
