Major Michigan markets
Michigan market context
Detroit metro's car culture means everything aftermarket-adjacent runs strong: tint, PPF, ceramic coating, wrap, restoration detail. Ann Arbor + the auto-engineering corridor sustain a steady premium market. Salt-belt winters drive paint protection demand.
Michigan film tint laws
Michigan allows 70% VLT on front side windows; rear sides + back glass any darkness. Windshield: top 4 inches AS-1 line. Medical exemption available.
SalesThumb's state VLT compliance check uses these MI thresholds at quote time. Out-of-spec selections trigger an auto-attached customer waiver to the invoice.
