Rattle can primer is essentially old school lacquer primer, and it is porous. So if you sand down the truck and spray it with spray can primer it’s going to get rustier. If you decide to spray it later with catalyzed automotive paint, all the lacquer will have to come back off or the hardened paint will lift it. Regular flat or satin black (or any other color) paint will coat the surface and keep it from rusting, but it will also have to come off if catalyzed paint is going on.

I did mine with John Deere Blitz Black which is just unhardened synthetic enamel like Rustoleum, but it is paint not primer. I needed something cheap that didn’t require disassembling the whole truck again, and this fills the bill for my needs, since it will remain this way as long as I own the truck.
