I know this was posted a long time ago, but I am looking for the spray paint manufacture/colours that match the Kubota orange and grey. Thanks for the reminder!
Ace Hardware carries a Machine and Implement Rust Stop spray enamel that matches the Kubota orange perfectly (to my eyes). Sells for about $5 for 15 oz spray can. Don't know about gray.
I guess all the Ace Hardware stores are independently owned, but I asked my local Ace Hardware for the Machine and Implement paint and they not only didn't have it, but said they had no idea how or where they could get it.
Go to a dealer, i just bought a can the other day. $7.95 for spray paint. just make sure you get the right orange. There's Kubota orange for the older styles and the new one is Kubota II. Not sure what year they changed the colors...
Dupli-Color 1620 Chevrolet engine enamel is a perfect match for the older Kubotas. I used it on my 1994 B2150 and repainted a rear blade with it. Cheap and available at Mejier and some other chain stores. Saw it on this forum last year..
