I'm guessing the pink "RV and Marine" antifreeze wouldn't be okay
to run in a closed cooling system with a radiator, but for just
winterizing a boat motor it's okay isn't it? It says it won't
hurt metal or plastic. Will it hurt gaskets or rings or anything?

I used it for years when I lived in the North East with no problems.
Given the choice I'd recommend spending a little more and buying the
type rated at -100 degrees. My thinking is that even if it ends up
getting diluted by residual/trapped water, you still have an extra
margin of protection.

It'll do.
