If Shaber has the time to do 'em, I'm sure they'd come out really well done... however, when I asked about painted side skirts (the 1st time my car was in there), Bruce shyed away from wanting to do the work because the side skirts were textured plastic, and he didn't think he could get the paint to stick to it as well as he'd want it.
You see, Bruce is a perfectionist... For example: he didn't think the paint would be smooth enough on my hood, so he chemically stripped all the old paint before priming and re-painting it. And my front bumper was so hammered from cones and curbs that he repaired all the scratches and dents on it before painting to make sure it would be smooth as well. Plus he pulled some dents out of my fenders before painting. And he didn't charge me or the insurance company extra because he said "well the insurance was only covering the sand damage, and I didn't want to paint the car w/o fixing those things 1st".
So, my guess is that Bruce's work would be second to none on the side skirts, but you might have to talk him into doing the work.
