Scratched rear lens.

[conny]

The rear lens on my wifes Citreon Picasso has a few scratches across the clear, (reversing?), section. She watched a video on how to remove them on YT which involved various grades of wet & dry paper and finally polishing with a drill driven buffer pad.
Does this really work and, if so, do you need any 'special' paste as a cutting compound?
Or is it a fake and she will need to buy a whole lens unit?

I knew there was a recent thread...

Headlights oxidising

My headlights were turning yellow, saw many vids showing how to resolve it, the only one which involves 5mins per headlight and resolved it was Armour All Headlights restorer. All others required buffing and using a drill with more elbow greasefor 2 hours, but for 10 mins , you cant go wrong...

Yes, it can be done. I've polished up scratched perspex by this method, finishing off with Brasso.

...although for exterior use, a sealer is essential.

That seems to be for lenses which have oxidised though. What she has are actual 'gouge' like scratches.

The odd deep scratch shouldn’t affect the MOT if that’s a worry, but a clouded lens could be.
If it’s a red lens then white light mustn’t show through.
The lamp units are available from motor factors at a reasonable price which you could consider.....it could take a good while to polish those scratches out, but of course it is possible.

I wouldn’t bother about the scratches, as long as there’s no white light showing, it should be ok. unless it is really unsightly?

 

[conny]

Thanks guys. It's the reversing light so it will be white light anyway.
Think I'll have a look at replacing the lens cover. Much easier than spending hours polishing.

Sadly it will probably be the entire lamp shell you'll need - minus the bulb holder unit which is separate of course.
Motor factors are much cheaper than main dealers, and I've never had a problem with these pattern parts.

You can polish out scratches with acrylic bath scratch repair paste.

Sandpaper out the scratches and then polish with compound. Compounds are just paste equivalent of sandpaper for fine sanding.
