Radiator Paint
I replaced my radiator a while back because it had a leak in its upper neck, and I couldn’t find anyone to repair it. All the radiator shops I contacted near me only replace radiators nowadays.
I finally found a radiator shop about an hour away what still repairs radiators, and I got it repaired today. However, the guy didn’t want to mess with painting it. Would this paint be suitable for painting the radiator?

Re: Radiator Paint
Pretty sure you can use any paint you want. An unpressurized radiator can never get above ~212° due to the laws of physics. I'd focus more on choosing something that's aesthetically what you want (gloss vs matte) and will adhere to the surface.

Re: Radiator Paint
Actually, an unpressurized radiator with 50/50 antifreeze in it can get much higher than 212but not that much to worry about.

Re: Radiator Paint
Use a paint that goes on thin. Maybe Rustoleum Bar-B-Q. The thick enamels will act as insulation and stop the transfer of heat and the engine could over heat.

Re: Radiator Paint
Good afternoon...Were the radiators painted originally...I seem to remember in 1963, my 30 Coupe Radiator did not have any paint on it...perhaps it was a replacement...even in those days...Ernie in Arizona

Re: Radiator Paint
Radiator paint is a special paint so that it does not limit heat transfer.

Re: Radiator Paint
A light coat of lacquer is what I use.

Re: Radiator Paint
Our local Home Depot generic flat enamel, $1 / rattle can for the core. Easy to blend and touch up. It doesn't come out thick and not much acetone in it like Rustoleum and the others. Place cardboard on either side of the radiator and/ or mask if core is mounted.
