deeveus 81 Report post Posted May 18, 2014 Anyone got any tried and true solutions to restoring headlamps I.e removing the yellow off? Was told by one person to use autosol but thought I'd try here's first in case I make a balls up of it. Cheers. Quote Share this post Link to post Share on other sites
nick496 268 Report post Posted May 18, 2014 On the work corolla used Brasso to clean them up. That was about 6 months ago, and they're starting to cloud up again. I think there is an actual pack that removes the yellowing, then you apply another product to create a protective coating. I'm sure someone else has had some experience with that around here.

KwS 2425 Report post Posted May 18, 2014 Ive had some success with Meguiars PlastX for clearing the lights, but never had a car long enough to see if it comes back. Ive seen people get really amazing results with wet/dry sandpaper, but too risky for me. Quote Share this post Link to post Share on other sites
elmarco 56 Report post Posted May 18, 2014 New lenses are the only real way to stop it. You can delay it but the fundamental problem s that polycarbonate yellows with UV exposure. The lighting manufacturers put a coating on the lamps which gets damaged - and exposes the PC.... Ive heard of kits with a spray on coating but its never going to be the same finish as the original one. You also need to be wary of cheap nasty halogen bulbs or HID retrofits as they can both have much higher UV content & do the same thing from the inside out. If it was me, i would try to find some new lamps (or just lenses if they are clip on). If thats too diffcult or mucho dinero, then try a kit with a sealer.

twisted 45 Report post Posted May 18, 2014 Sand headlight, buff with compound then polish then clear coat. Autosol works ok depending on how bad they are, but the sand, machine buff and clear coat method works best and will last. Quote Share this post Link to post Share on other sites

I am also just about to take my headlights to GT Refinishers to be cut and re-cleared. Will take before and afters. Quote Share this post Link to post Share on other sites
