Any thoughts about using automotive coolant for winterizing things like the following the macerators raw water pump toilet and holding tank. I will use the pink RV stuff in my fresh water system but its protection level is not as good as actual coolant. I can and will pump it out into my shop so very little will ever be killing willie before hes release back into the wild to be ran over by a cruise ship.
