Give radiators a factory-quality finish without affecting performance by choosing Eastwood Radiator Paint in Satin Black. Normal engine paints are too thick for radiators; using them will interfere with heat transfer and block airflow over the cooling fins. Also, standard paint tends to flake off metal radiator tanks. Withstands 150°C (300 degrees F), also suitable for heater cores. Acrylic enamel (85% gloss) 340g aerosol. 1 can covers about 6 square feet. Available in Gloss or Satin Finish .
