Purpled film on driveway regulars
Why it happens here
Dyed film's color layer breaks down under UV, and Lilburn's outdoor-parked cars take decades of it. Three to five hard summers start the shift; twenty finish it.
Our approach
The dead layer comes off by steam, the defroster is tested while we can see it, and carbon or ceramic takes its place — films whose color is structural, so a purple sequel is impossible.
