Someone must've listened as the pop-ups I always saw are now gone also.
As far as that being labor intensive, I would take a wild guess and say that it will only for the 1st time. (?) The worst part, I would think, would be the waiting so try to put it on as soon as you get there. I would also think that after it's dried and time to wipe, get the doors completely wet before trying to "scrape" it off. I use the green scrungies on the glass shower doors with no problems at all but if you're afraid they might scratch the surface, use the cheaper 1's that don't scratch anything. They just might, in this ONE instance, take the grout like cleaner off the door easier than Magic Erasers.
I have my glass doors pretty much mastered but would be very interested in knowing the name of the product he bought!! Always nice to hear a somewhat thumbs up review! Also interested in hearing what you're favorite SS cleaner is. I use Weiman's but it leaves a film and I have to wipe the appliances down twice. I used to love Rubbermaid but they changed the cap from white to black (or reverse) and what they really did with no announcement was change the formula. (By change, what I believe happened was added water which not all SS likes.) I wrote Rubbermaid (this was years ago) but I apparently didn't contact the correct Rubbermaid. (?) Ohhh Kaaaay! Anyway, without buying a full bottle of 10 different cleaners without pre-sampling, I'd like to get more reviews of what people like. (Commercial cleaners only~nothing green.) Thx!
