CS30 un pinakabit ko sa WS ko. no "ghosting" effect so far. i was supposed to put CS20 kaso the installers warned me on the spot about the "ghosting" effect of the shades lower than CS30.

from what i understood, it's related to the thickness of the ceramic film. CS30 is the thickest film which can be attached a glass with some significant degree of curvature (i.e. front/rear windshield). pag sa sides, there should be no problem with the thicker films (i.e. CS20, CS15, CS05).

if you're worried about privacy, i can attest din that the privary aspect is still there with CS30 sa WS especially if the passenger window tints are darker (as advised by the huper optik guys)

i'll eventually have my rear windshield tint replaced with CS30 din. ipon ipon muna. currently, i have 3 kinds of tint sa tsikot was/still worried my defoggers will get cut.
