Stek PPF?
#2
My neighbor has Stek on his Tesla and I honestly can't tell the difference beween Suntek (which I have on my RS) and Stek -- both hydrophobic and very clear.
#3
I have it on my Urus and you can't tell there is anything on there. I have expel on my 720 which looks good as well but not quite as good.

I have Stek on my GT3 and feel the film is a little soft. I have used other films 3M, Durashield, Expel ultima. The color transparency of Stex is excellent and I have not seen any change so far. My rear hips have really taken a beating so it is time to replace it just after one track DE season. I know 3M has a new film it may be worth looking into.
