I haven't had a vehicle tinted aftermarket so this is my first experience. I researched this and found it to be a reasonably reputable brand and film type.
Marathon - AUTOMOTIVE | Johnson Window Films
From what I gather, as long as you avoid the cheap stuff that will transpose dye to your windows and as long as you don't get a metallic film that has been known to interfere with electronics, there are a number of brands with good offerings. Many smaller tinters seem to prefer a specific brand while some of the larger shops have a variety to choose from.
The color is a pretty good match to factory, which I like. The guy is close, comes with a lifetime warranty and he does good work.
Again, not an expert, so I'd be happy to be enlightened if I've misrepresented the validity of my findings.
