I haven't had to tint in a long time, is Huper Optik still awesome? I had that on one car that I had to sell, and it was pretty sweet for heat reduction in AZ.
It's still an option, yes. There doesn't seem to be a consensus winner.
And our heat is as bad as Arizona's. The oldest car I still own with Huper was bought end of 2007 and the tint is still perfect.
