I've heard mixed reviews about Sun Tint. most seem to be good experiences but one friend of mine had his lotus done there and said the job was so terrible he had to have it redone at a different shop.
I also received a quote from a guy in San Antonio who will come to Austin but uses precut pieces ( not custom ) and he quoted only $695 for the bumper and hood and front side panels. He uses 3m for lighter colors and Venture for darker. Haven't been able to find any good info on him though.
I'll keep researching and will repost if/when I do find some solid referrals.
