Makes glass look like new too
Had a sliding door badly scratched by dogs.  Used this glass wax and noticed a 90% improvement in appearance!  Definitely recommend.  It does have a very thin consistency compared to a product I used years ago, but it did the job.  I just did it yesterday - and note you don't have to wash the glass before you do it, although I cleaned off the worst - so I don't know how it will last.  I had 2 new windows put in a few months ago so used it on them too, hoping to prevent more water spots on the outside.  Very little elbow grease involved.  Glass wax is awesome stuff.
