hello, So this year i'm down on weekly cut customers for grass and i think there's room to expand into seal coating. I'm looking for an entry level sprayer, and i think i found a halfway descent deal on-line. http://store.asphaltkingdom.com/AK2200-B-Pavement-Sealcoating-Machine-p/ak2200-b.htm , this sprayer comes with the motor, wand, 50ft of hose and the pump agitates as it goes. If i were to buy this machine what else would i need to get going? a barrel of sealcoat, a wire wheel for my sthil kombi edger? some cold crack patch and some degrease? And pricing, materials x2 a good rule of thumb or more? or less?
