If they aren't too deep, go to an aircraft supply house or FBO. Aero Shell packages a plastic polish (for aircraft plexiglass) that puts an unreal shine on canopies. Deeper scratches can be buffed out (carefully!) with finer and finer compounds and finish with the polish.

Novus plastic polish does wonders as well for removing scratches.

I used Maquire's Scratch and Swurl remover (automotive product). It also works on the cars!

If the scratches are smal and superficial, you can use Future floor wax... Also Future can be used after you use progressively finer sandpaper and polishing compounds... Fills in the last miniscule scratches....

Sand out any roughness with fine sandpaper then paint on a coat of your favourite clear gloss. It will take about ten minutes.

there is soft-cut, a fine liquid compound it works very well with plexiglass. I use it on my full sized plane and makes the windows look new. you should be able to get in an auto parts store

GHS Guitar Polish. Removes scratches from pick-guards and leaves a haze-free static-free finish. Any music store has it. Works better than anything I've found, excellent quality. It's the best final detail polish for plastic or hard gloss paint.

??????? I tried some of these ideas recently with NO luck. How long do you guys rub/polish with these scratch removers. I tried some Maguiers and toothpaste. Both left the pastic hazy with very, very fine scratches in the plastic......looks worse than when i started. I cleaned this area very well and then painted a very light coat of Lustercoat clear onto the area. Now the area has a speckled, frosted textured look to it. I know....Lustercoat is not the greatest but clear should be clear.....right. The Canopy is for a 35% Pitts M12 and I'm slowly making it much worse than it was when i started. The original scratches/blemishes were not big or deep. Several areas only had "scuff" marks that I was trying to clean up.....lol..... HELP......

Unfortunately the plastic used to make the canopies does not take to polishing. It's too rubbery. You can only get a hard shine on hard materials. Try the Novus polish system if anything. Another thing to consider is spraying it over with Future floor polish. It is a clear acrylic and is commonly used as a gloss coat in model making. It removes with anything amonia based like window cleaner.

The Future is worth a try if your not up against nitro. It can be brushed on and still turn out the same. Its self leveling and easily removable if you dont like it. It will hide all the fog and fine scratches.

This may sound far fetched to some but we manufacture a product made from clear polycarbonate, when we are finished with most all the processes we perform on it then we sand it with 800 grit sand paper and clear coat with automotive clear coat followed be cutting and buffing as needed.

As Ed Smith and Sensi have said sand it (to remove wax and other crap), then shoot it with automotive clear coat. It sounds crazy, but you. Can not see through it at all when sanded, but as soon as you shoot the clear it will look better than new.

Hi!
As "High Plains" says! Sand it down with 1200 wet and dry sand paper and then spray it with 2-part acrylic clear.
I have done this many times.
If not satisfied ...sand it down with 2000-2500 wet and dry papper and then use and of the automotive paint polishing compounds available.
3M Finnes-it is just one brand, there are nay others-
Just wax doesn't remove any scratches.
