Night visibility
Dark tint on the front side windows makes it harder to see mirrors, pedestrians and cyclists at night. That is why the law limits front windows and why we recommend 35% or lighter up front on a daily driver. Ceramic film gives the heat rejection without needing to go dark.
The law
Florida allows 28% VLT or lighter on front side windows, 15% on rear sides and back glass for sedans, 6% for SUVs and vans, and only a strip above the AS-1 line on the windshield. Darker than that is a non-moving violation, and you may be required to remove the film.
Cheap film
Dyed film fades purple as UV breaks down the dye, then bubbles as the adhesive lets go. Two to four Florida summers. Removing it, especially over rear defroster lines, costs more than the film did.
What is not a downside with ceramic
Signal interference: KAVACA Ultimate IR is non-metallic, so phones, GPS and SunPass work. Heat: ceramic rejects infrared at any shade. Fading: it does not. Warranty: manufacturer-backed against bubbling, peeling and discoloration.
Bottom line
Legal shade, ceramic film, professional install. The downsides that remain are the ones you choose by going darker than you should.
