East Bay Auto Spa in Walnut Creek, he does good work and all tint has a lifetime warranty. $225(?) for 5 windows @ 18%. Very nice guy, knows a lot, and will compensate you if you aren't 100% satisfied with your tint job (that got me 70% on my front 2 windows hehehe).
Well WC Ford recommended I go there so it went through the WC Ford name. Might have done something, might not. But it's whatever, the only complaint I have is that there's one spot on my rear window with a batch of tiny, tiny, tiny bubbles and it annoys me only since nobody else can see them but me. That's how I got 70% on my front 2 windows as compensation.I sent a fellow Audi enthusiet there before and they totally messed up on an 06 S4 Avant. They did stand behind there work and re-did the entire job though.
