The reason I started this thread was to get info on the removal of
Diamondite polymer glass protectant. After receiving this info I proceded to remove ( using methyl acetate I had at home - worked as advertised) and discovered an somewhat unexpected result. The Diamondite actually did protect the windshield!!!

.
I had noticed some increasing apparent glass marring ( minor chips) and just wrote off to driving in the "real" world and possibly to the age of the glass ( original >8years old) . But ole and behold this marring was actual only in the 2 coats of Diamondite not the glass.

but pleased. Also some linear marked were removed by this solution.
After a little thought, it is obvious that a clear polymer, like a clearcoat painted surface is not completely resistant to marring during cleaning and wiper usage.
I am over-joyed by this discovery and functioning of this product.
To re-answer the above question about the value of Diamondite.
YES!!!
Was it worth the effort required to apply ( see my review from earilier this year. Again
ABSOLUTELY YES!!
Will it work as well on a daily driver

? Probably Yes with more frequent renewal.
Now time to play with the Zaino Glass Polish.
