I used the paint from Carter on my 53 one ton, and it looks pretty nice. I had to buy the hardener from my local paint store, but the finish came out very hard, and dried quickly. I've only had it on there for a few months, so I don't know how it will stand up to weather, but it sure is pretty now.
By the way, I ended up buying his paint because I wanted a color (burgundy maroon) that was only offered that year, and I couldn't find anyone else who could get it for me.
I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur ( https://timwhiteblues.imgur.com/
). I live way back in the woods in the Ozarks on 40 acres at the end of a 2 1/2 mile private road.
