The difference between a few months and a few years is one step most people skip.
How long does headlight restoration last?
A professional restoration with a quality UV-blocking topcoat typically lasts 2–3 years or more. Kits without a real UV coating often re-yellow in 3–8 months because sanding removes the factory protection and leaves bare plastic exposed to sun.
Make it last
- Park in shade or a garage when possible
