Cromadex 222 One Pack Fast Air Drying Alkyd Topcoat Aerosol can be mixed to many RAL, NCS or BS colours including some metallics in an eggshell, semi gloss, matt or gloss finish.

Assuming the radiator is bare, clean, dry, sound and prepared as detailed in the technical data sheet this could be used once primed with Cromadex Super Build Primer Aerosol.

Please note as these are solvent paints they will smell during application, curing and the first few heat cycles.
