I use the spray bottle that came with my "kit".. You can use any spray bottle, although I am not so sure I would use a large pump sprayer..
I usually do a smaller ( 2' x 2' ) section at a time, I found its easier that way... The large pump sprayer may cover too much area at one time.
my process -
I spray a 24" x 24" or 1 section at a time, spread with clean cloth,,, wipe and buff with separate clean soft cloth. repeat till finished.
I found it works better if spread before it dries, less streaky that way.... The large pump sprayer may give you streaks.. perhaps someone else on here has tried that with success and can report.
