won't know for sure until you see it on person because the black paint can very. id imagine dark as possible...Question is will 35 blend with roof. Or 20?
25 is just perfect . 35 isn’t bad as I have the in my Q50. Wish I went a bit darkerI'd like the rear glass tinted to blend in with the black roof but also not look mismatched with the side glass. Definitely not after the ghetto look so will go for 35% all round.
