This SAE Recommended Practice sets forth a method for determining the compatibility of automotive sealers with cathodic electrocoat primer. This practice sets forth two methods for evaluating what effect, if any, an automotive sealer has on an electrocoat primer bath or the resulting baked primer coating, or both. Method No. 1 determines if a sealer's passage through the bath will "leach out" any material, from the sealer, that will then produce coating irregularities. Method No. 2 determines if a bath contaminated with sealer debris, 0.1% by weight, will have any effect on parts processed subsequent to the contamination
