He's not cheap, but does great work. About $800-$1100, depends on how far you want to go. I suggest I actually had him clearbra the painted area inside my wheel wells and the entire bottom of my back bumper. Also a good idea to do your sills.
I would assume you'd use the Venture Shield product, it's FANTASTIC and doesn't show orange peel as much as the older 3M stuff. These things hold up pretty well to yellowing in hot areas. Make sure you use Plexus on it since it helps protect against UV damage (he'll usually give you a free can of it and a microfiber cloth to maintain it). However, if you're putting this on a very light colored car that sits out in the sun a lot, expect that over a few years it'll definitely change color a bit. Also, avoid tire dressing on your tires, it'll eat up the exterior coating on the venture sheid product.
