The only thing I'm aware of is that the pink RV antifreeze usually doesn't have any rust inhibitors in it - I like to use the regular stuff with rust inhibitors for storage.

I was planning to use the "pink" RV/marine antifreeze but a friend (with a Catalina 28) says it is bad for the parts of the water pump. Is that true? What product do you recommend?
