Title: Sliding Glass Door Actually Slides
Review: I had a number of sticky windows and doors. Bought E450 and applied. Slickkkkk... they are all sliding now. I could not believe that it actually worked on a sliding glass door that I haven't opened since 2002 (slight exaggeration:)... however, even this door is now usuable. I've used the product for the past 90 days ... no complaints, works as advertised... therefore FIVE STARS !!!
