I didn't take any before and afters because I didn't think the end result would be that great...
--but--
I attacked my 2000 YJ's windows with Plasti-X (Meg's) using a mf applicator and working on small areas at a time. I tried initially to do it while on the Jeep but I didn't want to stretch it. Then I took the windows off and took them indoors and worked on them on top of a sheet on the floor. WOW. I did both sides fairly vigorously using the mf applicator and removing with a fresh mf towel.
Followed this with a dose of Plexus and a mf towel. The Plexus increased the slickness and shine dramatically. They almost feel waxed.
Overall, clarity increased 100%. I didn't have the courage to bring the PC indoors to work the Plast-X longer, but I'm very happy with the results by hand. Good Luck!
