Hey guys (and gals?) I'd like to add some tint to one of my machines that has no burn-in, since I think tinted looks better. I'm going to Wal-mart to get limo tint and do it myself as I've heard this is an easy way to tint already installed glass. What I want to know is, has anyone else done this and what level of tint to buy? 5%, 20% or something else? Thanks guys.
