Technical Rattle can blues

One of the guys on FB often paints several rigs a week using those purple HF paint guns and treats the paint guns as disposable. He buys them when they are on sale and says that they work great for one round of painting. You don't need a big fancy compressor you just need a continuous supply of air at the pressure you are spraying at.
Unless you just flat don't have access to a compressor I'd just buy a gallon of inexpensive paint and the flattener as the guys said and spray it.
Wrong color (s) but I have been highly impressed with the International Harvester spray can paint that you buy at the IH farm equipment dealer's part counter. I repaired and painted the nose on a leased IH tractor a few years ago for the dairy I was working on and that paint not only went on great and laid out nice it stood up to migrant farm workers spray washing cow manure off it with a pressure washer on a regular basis as long as I worked on that dairy. For a guy who had a small body low buck rod who wanted "just red" I'd suggest it in spray can or in the quart or gallon.

Ford tractor blue in the spray cans is shiny after it is sprayed so that won't work.

The other option is custom mixed paint in spray cans that usually come with the good nozzles. A lot of guys building choppers in Central Texas in the early 70's used custom mix spray bomb paint from Foster's paint in Waco. He is no doubt long gone as he was in his 40's or 50's then. You would have to hunt down a paint store that does it and it will probably cost 10 to 15 bucks a can now. A bit spendy but the good part is that you can get away with painting things with spray cans in places you might catch hell doing it with a paint gun.

Old time Waco TX area rodders will tell you the story about Laddie Segrest painting his 32 3 window with black spray can Gibsons true black from the Gibson's department store in Waco. In the 70's he told us that it was the blackest Black he could find. Spray, wet sand and spray some more until he got it the way he wanted it.

 

I've done all the body work on previous cars, and my brother-in-law has painted them. He can no longer hold a paint gun for long. He told me to pain the '39 Dodge I'm working on for my younger grandson. I've sprayed primer, no swat, but paint? I'm worried.
