Correct me if I'm wrong, but from what I have read, Bobcat does not use the same vendor for the backhoe as for the tractor. The tractor is made by daedong, which I think everyone is aware of, but the backhoes and loaders are made by someone different( I believe Rhino). I doubt that Rhino would change their paint process for the bobcat tractors.
What I don't quite understand about the paint issue, is the fact that these are built and painted right along with the Kioti tractors, and I haven't heard of the Kioti owners having issues with the paint. I wonder if the white just makes it so much more visible.
I work for a company that makes digger derricks, and aerial equipment for the power industry. Are units are painted white as well, and when new there is no visible rust, but after some time with nicks and scratches, the rust really stands out. It is never enough the be detramental the funtion of the unit, just kinda ugly.
