John Deere Blitz Black

Does anybody have any experience with this paint? Can you use a different hardener other than there brand? Something cheaper? Also has anybody used it out of the rattle cans? If so how did it turn out? I have a old Dakota I would like to paint It a satin black. I’ve never painted before so I don’t know how this will go. Just looking for some opinions on this paint or maybe another paint. A rattle can paint job would be ok for this truck also it’s a beater. Just want it to look better. Thanks
