IMO - the tint w/the vehicles does do crap for warm states, like FL. it's more just a privacy thing. In FL - 15 is limit on front windows. back and rear, no limit.
i needed to handle the heat better, so I did that LLUMAR ceramic tinting also...... world of difference. luv it.:banana:i was amazed at the difference when the window was opened and the heat thru the open section compared to the tinted glass. I like the additional privacy in the back.
i did:
front sides: 15
rear sides (added to factory tinted glass): 30
cargo sides (added to factory tinted glass): 15
rear (added to factory tinted glass): 15
