Purchased some POR-15 yesterday (ouch, a bit steaper than 'rust check' brand). The destructions state that a water-based cleaner should be used to prep the surface. Of course, they also pitch their own marine cleaner which my source does not carry.

Are they any alternatives, or a commonly used solvent, safe for POR-15 prep. I have a number of small areas (most on the front cross-member) to address now that the engine and steering box are out, most of which were coated with a film of various petroleum based substances.

Ive already cleaned brushed and wiped with rubbing alcohol. Might this be sufficient? I have no experience with POR-15.

Thanks,

Dave M
