Matching radiator Paint

Been there, done that. I don't recall what I used, but it wasn't anything special. I did once see a long time ago an offer from J.C. Whitney for special radiator paint. Claimed to match the color/glossiness best, and was a special formulation that left a thinner coat to better allow heat dissipation. But, I did mine four years ago and haven't had any overheating--even when driving through AZ at 113°.
