jusy because a block was hot tanked and degreased doesnt mean it's ready for primer , you did prime it right?? during the assembly prosess there's alot of lubricants involved!! the block should be degreased a couple of times b-4 painting also should be etched for proper adhesion i like using a good enamel paint and primer and baking the enamel with heat lamps to cure and when the engine is ready to run run it for a few short periods of time to further cure the enamel
