Just vanity on my part, I don't really like the grey\rust color of my calipers... was thinking of painting them silver or light grey..
I found a great how to article (C5 Covertte how to)... doesn't look too hard.

Just curious to know if anybody here has done this before.

done it. if you want it to look good then its a lot of work. take the calipers apart, clean them very acurately!!! dont touch them until they are dryed etc.
it is easy but it is also a pain in the ....
cheers

Thank you.

I considering doing when I'm due to change my pads.

i did it on my wife's grand am. use some brake cleaner or other good degreaser before you paint it. I forgot to clean the rears off before i painted them, and they looked like crap but the front ones looked great

I actually bought a kit...
