老美车版有人，用透明贴膜(Clear Film)贴整个前挡风玻璃windshield，隔热效果明显。

我自己考虑也想这么做，来应对德州大太阳...

Texas tint laws 允许用透明贴膜(Clear Film)贴整个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."

不知群里有人做过前挡tint没有？
