A close buddy bought a Chevy 1500 recently. A beautiful truck. On my very first visit after his purchase, I offered to take his hammer and put the first dent on the bottom of a quarter panel so he could be over that "new truck experience". Might as well get it over with. I suggested he do it, but he couldn't bring himself to do the needy.
After 8 Kubotas, I would have been "Displeased" about the hood, but really pissed with the overspray, especially on the radiator screen I have to clean 2x daily when bush hogging my fields. Any paint that made it through to the radiator would be a tech with a toothbrush cleaning it or a new radiator at no charge.
Then I would have considered the free services received. I'd still be pissed about the overspray. If I couldn't live with the crappy hood finish, as suggested, I would take it to a body shop to be repainted. I know I'd be turning the ratchet to deinstall the hood while questioning how long it would be before I scratched the hood (inevitable) with some branch and wondering if my OCD (CDO) got the best of me and my wallet. But if I cringed due to the finish every time I started the tractor (my problem), I'd get it refinished.
I'd use some mineral spirits to see if I could get the overspray off the hoses and other places the lazy tech, who couldn't take the 2 mins to find cardboard, sprayed. I've never seen a factory OEM part from Kubota with a bad paint job.
That Kubota model with cab is a sweet tractor for a small land owner and I hope you enjoy it.
