fwiw...the tire dealer in town filled a garden tractor for me with something he claimed was like Rimguard, but didn't make a mess. He showed me a beet juice mess and was quite animated about it.
No cold weather issues and no rust, ironbender.
Driveway here, has quite a hill and once iced over my unfilled Massey will not climb it. Neighbors MM has both rears filled and he went right up it--same day. Sliding sideways is a good way to die, filled with chains would be wise...
