Hey, wanted to ask all the engine guys out there about spraying down the inside of engine (cowling off) which is the best product for preventive maintenance against saltwater corrosion. My engine guy always recommended WD40 ( which I have a ton). But a quick Google reveals concerns about plastic with WD 40. Does Corrosion Block have the same concerns? Thanks in advance. Also, is it okay to spray battery terminals with either product??
