Z3 Window Sustainment

How does everyone here manage to keep their lovely rear windows looking new? Is there something that y'all do to ensure that the window doesn't scratch before putting it down or do you throw all methods out the proverbial window and just deal with it later?

I've owned my Zed for about 4 years and I'm not sure that I've found a solution to the problematic rear window yet, even after a top replacement.

Thanks guys.

You can get a "window Blanket" either BMW or aftermarket (or just roll up a towel)

Several plastic polishes can be used like Meguiar's Plastix

I have a high-thread-count bed sheet that I currently use, but even with that the dirt manages to edge away some of the cleanliness that the new top has. Only time I put her down is when I've just washed her.


I have some of the Meguiars and I've been to scared to use it on the window, should have tried it on the old one :\

Always use a window blanket or towel when you put the top down. I've found Meguiers #18 best for everyday cleaning and #10 and #17 for heavier stuff.( I just replaced my 13 year old original rear window that still looked great because the black trim around the edge started falling apart)

I use a microfiber towel so the plastic don't rub on itself when top is down.
