I thought I remember someone have good results with
Klasse AIO. The color runs all the way through the Deere green plastic. I have seen those plastic hood covers on ebay and they are not too expensive. I have waxed my LT155 but I haven't used any power buffers or polishes.
I have a few scratches I would like to get out. I would be interested in someone's real world experience and results. Maybe we can get a section in the Click & Brag for other.
