I'm so pissed. I've been real anal about my rear window and it had paid off -- not one scratch. On Saturday I decided to polish/and protect it with Plexus. Using a flannel cloth, I rubbed gently after apply Plexus. The outside seemed fine but when I repeated the process on the inside I ended up with whole series of hairline scratches. Either the cloth was dirty or it wasn't soft enough. Is there anyway of removing these or do I have to live with it?

 

Ditto here. I've done the Plexus/cloth thing with mine and yet it still has scratches. I just got the Muz mat and plan to install it soon.......and get the window replaced under warranty

 

Fine scratches can be removed/minimized thorugh the use of any number of excellent products for this purpose, such as Meguires #17, Honda Metal Polish (for Gold Wing plastic windshields) and a product from 3M (but I can't remember the name). Several quite visible scratches on my rear window have been quite satisfactorily treated with Meguires #17 followed by Plexus. And yes, it is very important for the cloth that you are using to be clean.

 

I second the use of Meguiar's #17 (Clear Plastic Cleaner) but was also told by the Porsche/BMW dealer to follow that with Meguiar's #10 (Clear Plastic Polish). It makes the plastic very clear and finishes polishing out the little scratches. Use the Plexus every week for routine cleaning and the Meguiar's every month to every other month for deep cleaning. I get compliments on my rear window at every meet.
