老美車版有人，用透明貼膜(Clear Film)貼整個前擋風玻璃windshield，隔熱效果明顯。

我自己考慮也想這麽做，來應對德州大太陽...

Texas tint laws 允許用透明貼膜(Clear Film)貼整個windshield.

Window Tinting Standards | Department of Public Safety (texas.gov)

"A clear (un-tinted) UV film is allowed anywhere on the front windshield without a medical exemption being required."

不知群裏有人做過前擋tint沒有？
