Here's how bike screens are fixed.
1. 400 & 1200 grit sandpaper
2. Soft cotton buffing wheel that fits to a variable speed drill
3. A burnishing compound stick (Jewelers rouge) Builders warehouse sells a pack of 5 or 6 for polishing different kinds of metal.
4. Autosol scratch remover.
1. Start with 400 grit sandpaper & sand in one direction. Try only to sand the area where you want to get rid of the scratches.
2. Once removed or in the case of really deep scratches, have repaired them to a more acceptable level, take 1200 grit sandpaper and sand again. After a while, the plastic will start to clear again. If you continue, you'll eventually polish until it's quite clear and smooth.
3. Fit buffing wheel to the drill. It's important to have a variable speed drill, so you can let the buff rotate slowly~ otherwise the fast spinning buff will burn the perspex. Apply some of the burnishing stick to the pad. It comes with instructions, but remember that you don't have to apply tooo much. Then apply some to the screen.
4. Start to polish the screen. Again, only polish in one direction and do not alternate directions. Go carefully & slowly and you'll see the scratches magically start to turn clear & smooth. Continue carefully until the scratches are gone. Some deep scratches are not possible to remove but you can still improve them a lot.
Hope this helps.

this is the type of method i was refering too. lexan should hold up just find so long as you use kiddy fingers. go slow, dont let materials build up etc....
i believe a similar method is used to make the lexan ul grips and ive used similar processes with fantastic results on several types of polymers. with more dense/harder plastics ive used light heat on a very well sanded(2k+) surface to just get that extra sheen, but for what you are looking to do polishing would be the easiest route unless you want to create a mold and make a set of grips from scratch
