to add to Peter's post.
It's not necessary to go 'full out' gallon can with sprayer.

I live in Maryland, where they do salt. pre-storm liquid (?) on the roads...worse here is Ice during commuter times so there are liberal applications.

for my 87 245, which I don't use to commute but does get driven in the winter, I hit it in the fall using the 12oz aerosol of Fluid Film. Hitting the lower seams on the doors, inside the rocker panels (the 240 has rubber plugs uptop giving access), rear springs and shock mounting hardware, lip under rear bumper, rear axle. and any where I find new nascient rusty spots. Hinges etc, anywhere you would use lithium grease or oil.

1 can does it, with left over to hit the snow blower.

Buy it at any John Deere dealer. $15...
