I am considering using Fluid-Film this year on a brand new Toro GrandStand mower. I've read a little about it and have heard a lot about it. My question is: after the first application, which would be on brand new clean paint, what is required in the area of deck cleaning for the second application next week (I am a homeowner)? I scrape away the grass clippings after each mowing, but do not remove the thin 'film of grass' that coats the deck. Would I have to get the deck down to clean paint before applying coats two, three, etc? Also, which Fluid Film is recommended for 'grass prevention' on mower decks--original or the thinner 'A' Fluid-Film? If I use the undercoating gun, can the Fluid-Flm be stored in it betweeen applications or does it have to be cleaned out each time? I thank you for your responses.
