I found the first Huper Optik tint installer in the Bay Area! I was wondering if any of you were interested in this information. He charges about $500 individually with Huper Optik in the back and V-Kool for the front windows. Contact me if you are interested in this info, as we might be able to get a discount.
The best part about these two films are that they are very good at heat rejection, so the insides of your car won't get as hot in the sun. The added bonus for the Huper Optik stuff is that it won't affect radio or radar reception like other metallic tints do. V-Kool is light enough to be tint legal, so its great for all of you who would rather not be bothered by the police.
Here's are links to the manufacturer pages if you'd like to find out more for yourself:
ps. The installer used to drive an 2000 S4, but upgraded his daily driver to an S430.
