Misted headlight

[DIYspanner]

Bora TDI

From what I've read, the UV protection layer has been eroded by the weather hence the misting of the plastic material.

Has anyone used this product?

Or perhaps fine grade Wet n Dry then glass polish?

T-Cut on a damp rag and a bit of elbow grease. If you haven’t got any T-Cut, toothpaste will do.

I had excellent results polishing off the eroded surface of my headlamp lenses (they look like glass but it's actually a clear plastic) with Meguars.

I just bought a bottle of the liquid polish but you can buy kits at higher price.

The protective lacquer spray left a slightly satin finish. I think I would rather not have used it, and polished them again in a few years if necessary,

I tried various buffing mops but got the best results with a foam polishing pad in my cordless drill. The plastic foam holds the polishing compound without absorbing it or flinging it off. You can get a polishing kit with an arbour and a rubber backing disk.

You do not need to grind the surface away with abrasives

I can send you some pics by message but they are not to be distributed for privacy reasons.

You do need to mask off all nearby paint and other materials as the polish is very hard to remove once dry. I opened the bonnet for best access.

For £4 it must be worth a try, I had good results using fine grades of wet & dry then final polish. Finished with clear lacquer and it lasted a couple of years before I changed it for one from a scrap yard.

I had all the intentions of sorting my golf headlamps towards the end of last year, my research (including a screamingly genuine youtube review) lead me to buying the Meguiers Headlamp restoration Kit but you need to lacquer them after restoring to retain the UV protection and the lack of any dry warm weather ceased my plan to do them last year. This thread reminded me I have all the bits, I have the Plastikote Quick Dry Clear Lacquer from Toolstation.

I wouldn't use lacquer again.

I too used:

Meguiar's G2970EU Two-Step Car Headlight Restoration Kit with Headlight Cleaner and Headlight Protectant​

with excellent results when I needed to do it.
I got the kit rather than just the bottle as it contains all the sanding materials etc.
