plastic rear window scratch remover

what is the best way to clean and remove scratches in plastic rear window on miata soft top.can the plastic be replaced with glass?is their a replacement soft top with glass rear window?

This is a long-shot, but if the scratches aren't too deep, some toothpaste might work.

I have not personally used it but this product is popular in the boating world where they have similar "windows" on boat canvas covers.

I've used Meguire's on Miata back windows with great success. You need #17 Clear Plastic Cleaner, followed by #10 Clear Plastic Polish.

I use Plexus plastic cleaner and polish. Works very well on window tint and I use it on the flexible rear window in my convertibles. www.plexusplasticcleaner.com

I used one of their kits to shine up some corian countertops. It worked great.

The Novus stuff is good. It's a "step" - type process too.

Meguiar's has a new product that eliminates the old "2 step". It's called PlastX Clear plastic cleaner and polish all in one.

I've used it on motorcycle windshields with great success.
