Does anyone out there have the solution to removing surface scratches on
4mm clear plastic?. I have tried using plastic, glass and even metal
cleaner, without success

Try using a fine grinding paste "toothepaste perhaps?" and then Brasso in a
circular motion.

It does work but you have to keep at it. :-(

Hi,

Google for PlastX, haven't used the stuff but would give it a try.

cheers,
Pete.

It depends a lot on the plastic. Acrylic (Perspex, Lucite) is easy.
Polycarbonate or ABS aren't too bad either. Some of the others are
much more awkward.

I'd recommend "Micromesh" abrasives, but they're not cheap. You can
often buy small mixed-grit kits, just for removing scratches from
expensive clear plastic canopies. CSM abrasives are my favoured
supplier for all such things, but even pilot shops like Transair have
these kits.

Anyone got a DIY method of polishing plastic (polycarbonate?) spectacle
lenses?

Pilot shops, like Transair at Shoreham Airport, usually sell kits for
getting scratches out of aircraft canopies.

I have used cerium oxide (a very fine powder) for polishing scratches
out of windscreens and windows. It takes hours but does work. I
imagine it might polish plastic OK. Don't breathe in the powder.

That's what you need for glass, but you can get away with simpler and
cheaper abrasives on plastics.

How did you do this ?
I ask because I have a supply of cerium oxide - and a couple of
fairly noticeable scratches on the inside of the windscreen on my
'64 Moggie Traveller (apparently caused by a diamond engagement
ring, as the wearer 'demisted' the windscreen !)

Can't decide whether to keep the scratches as a 'feature' - or try
taking them out by polishing.....

....did you use any mechanical assistance - or just elbow grease ?

Thanks

Novus is pretty good, popular for cleaning pinball playfields, Paddy
Hopkirk used to import it for cleaning cabrio hoods.

Best price appears to be Ebay at moment.
