When my original clutch master cylinder went out a month ago, I had a co-worker push me home. His primer white bumper left white streaks all over my rear bumper strip. I grabbed some Dupli-Color Bumper Coating spray and it works beautifully. Just be sure to tape a lot of the rear off because the spray is a bit wider than I expected. I'm a novice painter so I had some lite overspray and a couple of runs to go over onto my paint. In my panic I searched my house for something that would remove the overspray and runs. I ended up trying Orange Pummace Hand Cleaner because of the abrasive nature of it. Turns out it works amazingly well! It takes some serious elbow grease on the thicker runs, but it worked!

PS: I didn't even realize the front and rear strips are molded into the bumpers and just painted a different color than the rest of the bumper until after I owned the car lol! Just a little info for anyone that didn't know.

 

The moldings are not painted - in stock form they are left bare (black).

It doesn't stop retard body shops from painting them black and ruining the look, as they did on my rear bumper.

 

The side moldings on the SII and SIII are rubber and are not painted.

Best to maintain these by occasional treatment with back to black or some other treatment (I use vasoline, easy, cheap and lasts a long time).

Paint on the rubber trim looks phoney and will peel and look terrible after not too long.

The black trim on the front and rear bumpers, as Jan correctly points out, is actually part of the molded plastic bumpers and is painted, not real rubber.

Over time, they can get scratched and worn, just like any paint job. So they may need a bit of touch up every once in awhile.

Like after you get pushed home by a primer white bumper.

 

The black strips on the bumper skins are not painted. When you order brand new skins from Mazda they are masked off - only the top and bottom parts are pre-primed.
