I'm just getting started with my recently purchased 200 and want to finish the job that Toyota started by tinting the front windows as well as the rear gate window. First off, why did they choose not to tint the glass in the rear lift get? So bizarre, but I'm sure they have a reason. Everything I've read says 20% is a good match to the existing factory tint, and to avoid highly metallic tints. Safe to say the same applies to the rear? Any other advice or pointers? thanks. BTW I have a white 2009 w/ upgrade pkg.
