I just got my Z12 Glass polish today. This stuff is the best glass cleaner ever and I should know I tried everything. I had water spots (acid rain) that would not come off with newspaper/vinegar/lemon juice/clay bar/Stoners-(a very good cleaner except for water spots).
Zaino got all the spots off with about a knickel size spot of product worked over side window. Wiping off the product is simple and easy. Now my windows are perfect. Thanks for listening to my blabbering.

 

good review!
it is a good polish... i have also used it with the pc on older windows (be careful if trying this cause scratches or swirls can happen if you are too aggressive with the machine)

 

I have to add that Auto Glym Glass Polish is amazing also. It makes my windows look like they are almost not even there as there are no issues with this product.

Also if going out for a long drive carry a bottle of Auto Glym Fast Glass for those little touch up jobs.

Great products the pair

 

I agree with Kelk AG glass polish is very, very good

 

I have never heard of Auto Glym. Where can I get it, I like to try different products. Is the fast glass as good or better than stoners? Thanks guys

 

TF - I don't know whether fast glass is as good as stoners as we cannot get that in the UK but if you search for Auto Glym in google or go to this site you should be able to order it in America

 

Most mild polishes work well on glass. I always use 3M Swirl Remover and when washed Stoner's Invisible Glass. My point is just that you don't usually need to spend money on a purpose-built polish for glass. Glass is much more forgiving than clearcoat.
