Coating to Increase Heat Dissipation from Stainless Steel Surface

I want to increase the heat dissipation from the motor's body in stagnant air condition to reduce the temperature rise of motor coil. The motor's outer body is made of 304 stainless steel. The emmisivity of surface is to be increased by applying a paint with high emmisivity & low absorbity as there are more equipments radiating heat in the proximity. About 350 watts heat is to be dissipated from an area of about 0.5 meter square and limiting surface temperature below 100 °C. Kindly send your suggestions
