I'm looking to get the front bumper on my 5 year old black Z repainted.

It has some rock chips and scrape, and I thought it'd be nice to repaint the entire front bumper.

Is there a body shop/paint shop that you guys recommend in the East Bay?
Also, I know a guy who got some coarser paint used for his lip. Although it's not as shiny, it supposedly is tougher so it doesn't chip as much. Let me know if you have experience with this stuff.

Also, is using 3M clear bra the best way to protect it? I heard it eventually yellows and that once it's on, you can never take it off.

I'm planning to keep my Z for the long haul so any tips on keeping my Z look fresh would be great.
