Sticky feet are SOOOO important.
I found this out the hard way and the soles of my feet went dark brown it was awful!
Do not spray any client without sticky feet (Or bed roll)
They will be left looking like they have been dancing bare foot in the mud!
When buying sticky feet, make sure to buy the ALL over sticky surface ones. As the ones with just a couple bits of sticky back plastic just fall off and some of the solution still gets under them! Not good!
