Mobile Headlight Restoration in Salem, OR

The better ones can, if you follow every step. Yellowing and haze are the lens's original UV coating breaking down. Kits that only polish make lenses clearer for a few weeks or months before they cloud again; kits that wet-sand through the damaged layer and then apply a UV-resistant clear coat last much longer. Uneven sanding, skipping grits, or a thin or missing UV coat are the usual causes of poor results. Lenses with internal fogging, cracks or moisture inside need replacement, not restoration.

It depends mostly on whether a durable UV-protective coating was applied after restoration and how much sun the car gets. Polishing alone can fade within months; a properly cured UV clear coat can keep lenses clear for a year or more. Salem's sunny, dry summers do most of the damage, while parking in a garage or shade and washing the lenses gently extend the result. If a lens has been restored several times, it may eventually be cheaper to replace it.
