2k if done right is great, but no comparison to a good oem finish or for the most part oem paint. Most equipment paint dries harder and has much better fade and chalking resistance rhen your typical automotive paint. A favorite at the machine shop was valspar if no oem paints could be had. Cat paint and case paint seemed to be very good as well. Especially when the appropriate harder was added. Now we also use a greyco electrostatic paint system for application so it was fairly hard to mess up the application and for some reason laied down a very flat smooth paint job. I have to pay a lot more attention when using a standard hvlp pain gun to get the same results.
