I did this way back in 2008 for something to do, and to alter the way the back of the car looks. the DIY to remove the rear bumper can be found HERE (http://www.ephatch.com/forum/showthread.php?68073-DIY-Rear-Bumper-Removal).

-I created a work station outside of my garage to wash the bumper. it's nice to have 1.5 sets of stockies laying around. painting:

-I removed the side markers so no water would get inside them since I washed both the inner and outer sides of the bumper. I figured it would be a good idea.
-after the bumper was clean, I dried what I could with my shammy towel and brought it back inside to fully dry.
-I had time to kill, so I moved the car outside and washed off the unseen parts of the body for gits and shiggles. before I went hose crazy, I placed my dangling bulbs in the vents under the tail lights so no water would creep inside the bulb sockets doing any unwanted damage to my EP.

-I then set up my work station in the garage with a piece of plywood on top of the wheels so they'd be protected from the paint. put some more cardboard over the plywood, and I tossed two jackstands on top to hold the bumper higher so I wouldn't be bending over as far.
-once it was dry, I began to tape it up with thin masking tape using 2" pieces or so.

-I followed the line on the bumper with the tape, then covered the whole thing in newspaper because overspray looks like crap. the pics aren't clear enough but the line I made with tape is perfect.

-after it was all covered and ready, I ran two more lines of masking tape overlapping half of the existing tape line as my edge, then again so I had a fairly thick line of masking tape between the paper and the painting surface. I figured there would be a lot of extra paint hitting that line and I didn't want any to seep through the newspaper to the bumper.

-go into your kitchen and steal the nasty, old scrubbie wash pad that should have been thrown away months ago. you just gave your wife a reason to open a new one. lol

-get scrubbing. I scrubbed it for 10 minutes or so.
-after you think you have scrubbed enough, blow off your paint surface and prep your paint can.
-apply the first coat after you have made some attempt at ventilating your work area. I grabbed a fan from the livingroom and had it blowing air out of the mandoor, while I had my baydoor open a few inches to draw fresh air in. wear a dustmask if you can, or paint outside.

-I didn't scuff after the first coat, and it looked really smooth to the touch. don't touch it.
-after coat number one dried, I hit it again and scuffed it using the same scrubbie pad. after the second coat dried, the paint started to look textured. scuffing it removed that textured look. I did one last coat and let it sit for about an hour before I started to peel the tape off.

perfect line:

-the tape came off the bumper very easily, and there was a few spots that kind of wanted to come with the tape since it was still a little rubbery. this was a good thing because I was able to run my fingernail along the bumper crease to set the paint where it needed to be. now, I am not a perfectionist, if I was I would have paid a body shop to do this for me. I figured if it chips or peels, I will repaint it. and it doesn't need to be perfect since it is really out of the way and hard to see in the first place.
-I let the bumper sit a little while longer, then reinstalled the marker lenses.
-I pulled my car back into the garage after I aired it out and swept everything the floor.
finally time to re install.
-resort back to the rear bumper removal DIY. HERE (http://www.ephatch.com/forum/showthread.php?68073-DIY-Rear-Bumper-Removal)

I have one pinky fingernail sized peel on that lower edge all the way at the bottom which I noticed about 6 months ago. so this lasted about 3.5 years before needing any touch up work.

I did this almost 2 years ago, still holding up just fine. Great DIY!

thanks man. for what it costs/long it lasts it was worth the effort. next time I pull the bumper to fix the blemish, I'll use something a little more abrasive before paint. looks great on VBPs.

Nice, always wondered how that part looked painted. I guess I'll use the plastidip sitting in my garage.

lol @ scrubbing textured paint. that just means you sprayed it a bit too light/dry for your tastes. all you gotta do is lay down another wet coat to smoothen it out.

If anyone else cares, when you're spray painting things, even professional spraying, you lay down a light, dusty coat first. Doesn't matter if it covers the previous color all the way. The purpose of this is to give the next layers something to bite on besides a scuffed substrate (a fresh coat of primer doesn't need to be scuffed/sanded if its been less than 24 hrs typically, as soon as solvents flash off/dries you can paint right over it). The subsequent layers you put on after will be full and smooth. You never want to scrub the pigment layer. If you happen to lay a nice coat and its turning orangepeely after about a minute, you can lay another wet coat to thicken it up and smoothen it out (typical of rattle can paint, not professional paint so much). I know this is the bottom of the bumper, but for practice, you don't want to touch the pigment layer with anything because you will contaminate the next layer (if you have one) and ruin your finish. If you're going to clear coat it, don't worry about pigment orange peel. You can fix the orange peel in the clear later. It's easier to work with.

Nice write up! You can also use PlastiDip. I did mine with it and I didn't have to scuffle it up. Just taped,cleaned ,sprayed and if you don't like the results you can peel it off.
