Can't find stripper?
Aircraft remover comes in two flavors, regular and low odor.
In my experience the low odor stuff works about the same as the stuff at Home Depot, the regular works better.
I know it sucks dealing with the nasty stuff (I.e. Regular Aircraft remover), but there is advantage in being closer to being done with one application. (Over and done).
My guess is it will take about 6 gallons to cover a 31 footer once.
