I used this kit on my lights and it works well.
One light had the clear coat intact and it worked really well. The other light had chips in the clear coat so I used the solution and buffer to "burn" off the clear coat (applied more pressure). Once the clear coat had come away, I used the solution and polished the virgin Perspex. Not sure how it will last with the clear coat gone...

I've just tried to polish the cloudy glass on my 1999 Bongo's headlamps, but the Xerapol seems to have made it worse! I followed the instructions and used plenty of elbow grease but they now look uniformly cloudy rather than patchy. Any ideas where I've gone wrong and how to make them clear again?

Keep polishing and it should improve.
I use some t cut type stuff from Auto Smart its like liquid with a talk type stuff in it and its excellent also did the wind deflectors.

I'm not familiar with Xerapol but, though your result is scary I'm sure it isn't the end of the world. I watched a youtube video where a guy took his lights back to opaque then with increasingly finer abrasives and polishing compounds brought them up to "like new". Can't claim to have been that brave myself though!

I restored the headlights on my Astra van using progressively finer grades of wet and dry, then polished up. The wet and dry stages were pretty scary, but they the lights looked like new afterwards.

From memory I started with about an 800 grit and went up to 3000 grit, all used wet (and soaked first). Then polishing off the 3000 grit cloudiness was easy with some regular polish.

It's on my to-do list for the Bongo, got to get it running first though...

T-Cut do a lens restorer which worked here on my car. Has a sealant to apply after which seemed very much like water to me.

I used T Cut, and then Fast Glass from Autoglym,
T Cut is not recomended for plastic lenses but Fast Glass is,
I found the only way to clear the lense was with the T Cut though,
The fast Glass removes any harmfull chemicals contained in T Cut.
Fast Glass on its own should maitain the plastic lense, I hope 8)

T Cut do a special headlamp restorer kit, that is OK on plastic. ordinary T Cut is not recomended.
I do not know what the difference is.
Whatever I have tried they seem to go yellow again after a few weeks.

Has anyone got a solution that keeps them clear longer? 8)

I used Farecla fine cutting compound on mine, with a 3inch battery polisher. VERY gently, a little at a time, wipe the lights with a damp cloth before you start polishing because it makes the polish go further and isn't quite so harsh... Rinse and repeat until satisfied then polish with ordinary Autoglym polish...

VERY gently is the key - it's very easy to press too hard and make them worse! Carefully around the paintwork too..

About 20 mins-ish a side and all done :mrgreen:

I did mine a couple of months ago and they are just as good now :D I'm hoping that a quick polish every year just before MOT will do the job...
