hey guys, Let me clarify, ALL of toyota's glass include at least a 2% colour, the maximum allowed (in WA anyway) is 38%. The Privacy glass on the rear of the klugers are darker than what you can legally get tint, so they will never match unfortunately. As for the UV protection of the privacy glass, i don't think toyota would leave it completely unprotected from UV rays, i would have to double check that detail. Worst case, most tint outlets offer a clear tint for UV protection, but some outlets will not want to touch the privacy glass. Hope this helps.
