I did paint them and repaired a few breaks two years ago. I actually plastic welded on two of the tabs that had broken off as well.
When I took the bumper off this weekend there were a couple more breaks in the plastic. The rattle can paint job looked ok from 10 ft but now that I'm getting new chrome thinking the new parts are the way to go. also,one of my hockey sticks has some pitting. Thinking it's time for some fresh makeup
