I've just made a headlight cover out of perspex but right at the end spilled a bit of solvent welding fluid on it which has marked it slightly. What do you use to polish perspex to transparency?
you could try brasso it polishes prespex nicely
People used to recommend that phone screens were polished with brasso and fine wire wool.
I have never tried it but its worth a thought.
We used a buffing mop and Farecla compound on a scratched bike headlamp and it fetched it out, you might have to use a couple of grades though.
Drawing a stanley knife blade across the perspex, with the blade at approx right angles to the surface, can work surprisingly well, particularly good
on edges

I have heard you can use toothpaste,although I have never tried it myself.
DON'T USE BRASSO!!! It contains ammonia which will cloud ant acrylic, Farecla G7 or similar
tooth paste works well on CDs and phone screens. might take a loooooong time to use to polish out the headlight covers. but maybe with the use of one of those polishing attachments on a drill/dremmel or something?
1200 grit paper removed the mark, cutting paste knocked that back to a haze and toothpaste restored the transparency. Not 100% perfect but good enough. Thanks chaps.
have you got any photos of the light units so far now?
No, no, NO do not use fine wire wool on any account. Only use a very fine wet and dry if it is badly marked and with loads of water and soap. Try Solvol Autosol or T Cut with a soft rag then you could try some toothpaste if you want to realy buff it up.
depends on what you mean by trasnparency. I have used toothpast as well asthe farcled compounds, the very fine stuff too but when the item is examined closely, there are still very small marks visible so I hjave never got it as good as new.

I've used Autosol with good effect on plastics before. After that a bit of toothpaste as mentioned should do the trick!!
