Kits work for a while. Here's why they usually don't last.
Do headlight restoration kits work?
DIY kits can temporarily clear hazy headlights, but most fail within months because they lack a durable UV coating and hand sanding is uneven on curved lenses. A professional restoration uses multi-stage machine refinement and a UV-blocking topcoat for results that last years.
Common DIY mistakes
- Skipping sanding grits
- Sanding too aggressively
- Taping poorly and scuffing paint
- No UV sealant afterward
