Fix scratch in plastic window?

you might try auto product used for cleaning plastic headlight lens. test with small amt on Q-tip for results. plastic insert should be removed first to protect shell

if you can dip the part, Future floor wax works great. I work part time at a local hobby shop, and I've seen a lot of our customers rescue old model car winshields using this technique.

I agree!  BUT... No store around where I live still carries it.

Meguiar's makes a plastic "cleaner and polish" for use on things like headlights, convertible top windows, plexiglass, etc.

Should be available at most auto parts stores or online.

You might try PlastX,  below available at Walmart.

It is widely used to improve scratches on audio turntable clear plastic covers.  You can then use it to remove the yellow and haze on the clear plastic automobile headlight covers.  I have been using it for both for years.  So you will find other ways to use up the bottle.

You may have already done this, but doing a search on eBay for 'lionel plastic dome window' pulls up a lot of things.  If there's no joy there, check with Jeff at traintender, assuming this is pre or post war stuff.

Hi plasticx is good too but I've used toothpaste and it works well also scratches require other methods and can take a lot of polishing and rubbing sometimes even need to use polishing compound if there are deep scratches!

Novus 2 Fine Scratch Remover for smaller shallow scratches helps.

Future floor polish is now sold as a Pledge floor care product but they have changed the name so many times I am not sure what they are calling it now (my bottle is a couple of years old and it was named Pledge Revive It Floor Gloss).

Try this on something else first, but I have flamed plastic back to clear with very good results. In the industrial world, it is referred to as "deflashing". Hot air can do it too. The part has to have enough meat to take quick hit of heat. Don't practice on a Ziplock bag! Put a score in a clear juice bottle and try that first!

Good luck!
