ABSTRACT:
Ethylene-propylene-non-conjugated-diene rubber (EPDM) parts having a defective paint job can be stripped with 100 parts of a solution containing 50 to 99 parts of sulfuric acid, from about 0.1 to 10 parts of a surfactant and from about 0.9 to 49.9 parts of water. The stripped part can be effectively repainted with polyurethane enamel provided that the stripped part is not subjected to the normal pretreatment required in painting EPDM parts.
