OK, I would sand it a little and then put some epoxy on it that I could sand again. Then, the black out is easy. You just buff the whole bumper with a sanding sponge and at the same time, buff your silver wings. Use painters plastic to make a surgical type of containment around the rest of your rig. I have done it several times and it works.
Finally, get you about 4 cans of Rustoleum flat black for plastic and use a very light coat technique (I learned alot about patience from Layonn!). It will take you a weekend to do the front end. It will turn out awesome and probably cost you about $75 bucks for the plastic sheeting, the sanding sponge, and the paint.
PM me if you want any more thoughts buddy!!! Layonn is a master rattle can guy! We ALL learned from Dragon!
