What's the best polishing product for glossy perspex/acrylic plastic? I need something extremely fine, and I'm looking for a polish to remove tiny scratches and scuffing, not a wax that fills them.

I've already tried the finest toothpaste I could find and it's too coarse.

In intermediate school we used braso to polish cut perspex ( we made perspex salad servers in woodwork )

Worked very well

The novus range of acrylic polishes are what a friend uses on his aquariums to get them back to totally transparent from when they are scuffed up.

Brasso certainly used to be the stuff for perspex etc. Think the supermarkets still sell it.
Its finer than toothpaste.

Think there are also polishes now for plastic headlight restoration that supercheap and repco sell.

+1 Brasso. But the professional thing is "polishing compound". Call anyone that sells a range and ask some questions. It is usually used with a polishing tool. I have used it on acrylics (the red bars iirc) with a random cloth and elbow grease with good results. It can be purchased from anywhere selling industrial abrasives. It is very very fine and feels and looks like wax.

I'm looking for a polish to remove tiny scratches and scuffing, not a wax that fills them.

So I'm thinking you might have some already.

If you want to remove large scratches you will need to start the process with something coarser. Iirc I once used Jif on perspex for this purpose but it was a long time back and the surface was absolutely atrocious to begin with. Ymmv.

I have never (or not on purpose) tried this before, but if you have a scratched off cut then run a heat gun over it (not too slow) to melt the surface into a gloss. Don;t use a flame, it will leave burn marks. I would not do it on headlights though, too expensive when it goes wrong.
