Heh heh, that figures. You guys spotted that tie-in right off!
I did try Liquid Glass once (on just a sideview mirror, so it was easy enough to redo afterwards) just to placate a Big Fan of the stuff. No thanks, heh heh, maybe I needed to do a dozen or more additional applications or something..
That "apply in straight lines" is a clue IMO...shouldn`t matter *one bit* what direction you do it. Straight lines only matter when you`re causing marring, and not too much then (depending on one`s standards).
