Bought a bottle of this a while back and couldn`t yield any results on the etched water spots on my glass (tried clay bar and even very careful with CLR afterwards) by hand with foam applicator. Now that I have a DA polisher, I`m wondering if it`s worth it for round 2 against my glass with this or if I should go down the 0000 grit steel wool path...

Thanks in advance!
