What do you mean theres no better place to do it? I watched a video i took them 11 mins to burn through with a random orbital in a single concentrated spot so that gave me some reassurance. I think canadian tire in my town sells chemical guys stuffI have done a few pieces of equipment with same results as the pictures. Painted steel or fiberglass with same results. Two step cut and polish then a sealer. Random orbit polisher, foam pads, etc. Done vehicles also and never burned any paint. It's farm equipment, if you are going to damage paint then there is no better place to do it. I suppose I could burn some if I really put a good effort into accomplishing that goal.
Years ago I ordered a bunch of supplies from an online distributor in Canada and use the Chemical Guys brand, something like a 2.5 for rougher cut, then a fine polish with recommended pads for each one. I haven't resealed/waxed since doing this work a few years earlier. Probably should but it is not high on my to do list.
I don't have enough hours in my life to dedicate to polishing farm equipment so wearing down the paint is never going to happen.
