am also not 100% sure if I have smash and grab. What i hav noticed though is that when I put my polarized sunglasses on, I see what almost looks like spots on tinted windows. Smash and grab/tinted glass looks different than untinted glass when wearing polarized sunglasses. (or so I think - either that, or my sunglasses are defective :rollsmile: )
But I am still not 100% sure.
