FYI... Caution... not all states will allow a fully tinted windshield. Florida is one of them. Since the vehicles did not come with factory tinted windshields, I can't claim it as "vintage exception", like with "no seat belts" or even "no turn signals" on older models. Check with your individual state laws. See below...
Florida's windshield tint law is relatively strict, allowing only a visor strip above the AS-1 line and requiring a high level of visible light transmission (VLT) for safety. In contrast, some states permit darker tints on windshields or have more lenient regulations, making it essential for drivers to understand their local laws to avoid penalties.
So, in case you don't know what the "AS-1 line" is, see below...
The AS1 line on a windshield is a demarcation that indicates the upper limit for legal tinting, typically located about 5 inches from the top. It ensures that the area below the line remains clear for optimal driver visibility and safety.
