Looking for a local easy to find solution head out to the local New Holland ( Ford) Tractor dealer your dealer will likely be Bob Mark New Holland in Lindsay or Sunderland and ask for the semi gloss
black used on the rollbars and the loader buckets. Very good product, can be mixed with acrylic enamel hardeners and reducers, made by Valspar and very well priced. I have used this for years and when I was the parts manager for the local New Holland dealer sold it by the case to all of the bodyshops and custom guys in my area...Comes in spraybomb, quart or gallon cans and will be on their shelf in stock... I know the JOhn Deere guys also have a blitz black that they use but I've seen it grey a bit over time, the New Holland stays nice and dark with a perfect sheen.
