The radiator shop here in town, that does all of or Bus, & truck radiators. Has said for years that reg. paint can cause overheating. Been in business since back in the 40's. So I believe them.
I've always understood that a thin coat of flat black paint is best for heat transfer and if you're trying to keep heat in then use an aluminum paint with a high solids content.
So what does the radiator shop use if regular paint is not good?
