Coming soon...DIY: Painting the lower part of the rear bumper to match body color

Painting the lower part of the rear bumper to match body color and some extras
I am not the first to think of this or even the first to do this but I thought I might paint the lower part of the rear bumper.
I've been an automotive painter for over 8 years now and I can never leave anything alone, I like modifying things but nothing over the top.
I took the rear bumper off my car tonight and I'm going into my work tomorrow to get a head start on Monday's vehicles and I thought while I'm there I would sand down the texture and prime the bare plastic to make it smooth, sand the primer smooth, and then paint to match.
The moderators may move this to the DIY section but for now I put it on the Exterior section.
I will post pics and you can follow my progress.
Thanks!

Interested to see how the paint holds up to the exhaust heat... kinda why they're not painted to begin with.
Not to mention in my opinion, ruining that contrast and making that section body color looks terrible. Again probably why its not like that to begin with. However, like I said it's just my opinion.

i like it when its gloss black... on BB cars.
PERSONALLY... id rather chuck it in the garbage in replace it with a rear diffuser.
Just curious, what grit do you automotive guys sand the primer down to?
I was considering "prepping" a car to get painted in order to cut down on costs, is it required to shoot automotive primer through a paint gun? or are those automotive spray paint primers alright to use since its being sanded down?
sorry for the threadjack

okay picture time...
I used DuPont's 2310 plastic cleaning paste and 3M's red scotch brite scuff pads to scuff the plastic. The cleaning paste contains grit to help scuff plastics and it cleans any oils or debris from the surface. Wear gloves with this stuff! It will dry your hands out like a ****! It will look like this when done.

Then I used DuPont's 2330 Adhesion Promoter over the now properly prepared plastic. This bites into the plastic and creates a proper coating for primer. It will be a grayish-milky color. Your bumper will look like this when you are finished spraying adhesion promoter.

The longer you let the primer set, the better. As the solvents evaporate out of the primer, it will begin to settle into any pits or scratches created when scuffing or maybe any texture left behind. I would say to start sanding with 320 grit and finish with 500-600 grit sandpaper. One thing that may help is to use 3M's Guide coat. It's almost like a fine charcoal powder. What it basically does it settles into the low spots and shows you how much more sanding you have to do. Some people may choose to just grab some rattle can black and do a very light coat over everything but I've never done it, so i'm not sure if it holds on while you sand the primer.
I will continue my writeup when I go to sand the primer and paint the bumper. But first I gotta find some steel mesh material...I have some sitting in my garage but the diamonds are going up and down instead of left to right. I dont think it would look right like that.
Till next time.
