Why Window Tint Turns Purple and Bubbles Over Time
Purple tint and bubbling are two different failures with two different causes. Purple means the dye inside a cheap film has broken down under UV, leaving only red pigment behind. Bubbling means the adhesive holding the film to the glass has let go, either from contamination at installation or from heat and UV the film was not built to take. Neither is repairable and neither is normal ageing. This guide explains what each pattern tells you, how dyed, metallised and ceramic films differ, and when failing tint stops being cosmetic and starts being a roadworthy and safety problem.
