Laughed when I saw this as I just did a JD L110 for my daughter-in-law while her husband serves in the Middle East. As you described, severe scratches, rubs and paint transfer. Got some use out of my foam cannon and pressure washer with a mix of various left over soaps I wanted gone just to see snow in spring. Used the Griots with Uber green and yellow along with products from Meguiars and Malco to get all but the most severe deep scratches out. LSP was Megs NXT 2.0. Dis-assembled and cleaned all plastic components with a Home depot product then treated everything with Megs Ult. protectant. Steamed the motor clean with the VX 5000 and serviced the thing with new blades, air filter, oil fiter from WW, synthetic oil and drive belt. She was flabergasted when I took it back and did a photo shoot to send to her husband. I smiled.
