I am getting tired of scrapping under the deck so I am thinking about buying a case of Mo Deck. But I would like to know if I can drive the mower up to the ramp, get under the deck and spray it? Or do I have to remove the deck and flip it up side down and spray? Of course I will be cleaning the deck before I apply Mo Deck. If I get Mo Deck, I will be taking the deck off and pressure wash the deck well before the first application, but after that can I just spray Mo Deck when the deck is under the mower? How often do you guys spray it between applications (hourly figure will be great).
