NeverWet sounds like it's worth a try but I found nothing about its "green" properties, if that's a concern. Much more, what does it do to tires?
Car wax and Rain-X are other options but require significantly more elbow grease to apply.
Then there's Teflon coated wheels.
According to NeverWet, their product outperforms the aforementioned products by a long shot but I'd be concerned about any chemicals that were superhydrophobic. For one thing, it doesn't like water. I mean, it appears to absolutely hate water!!! That's just not right.
PAM? I wouldn't use it on anything, much less a frying pan.
There is Ballistol...it's like CLP except it's "green". Not a hydrophobic product, it mixes with water, but I imagine it can't be any worse than using WD40. Aerosol or liquid(put the liquid in a spray bottle). It's also safe for other than metal products like leather, rubber, plastic, tires, wood, etc.
Check it out...it's not exactly inexpensive, tho'. If you like it, it's also available in buckets and drums but not from this website.
Great first-aid anti-septic, too, but our government won't approve its medical use. The medical grade version is overseas only...I think it has pain-killer in it.
Some people can't stand the smell(kinda like licorice) but the odor dissipates shortly after application.
Oh, you wanted a sales pitch?
Spray your fender wells with Ballistol before you get your Jeep muddy. Hell, spray the whole undercarriage!!! It's green and keeps it clean!
I wouldn't be surprised if it returns sun-faded fenders and trim back to black, either.
Seriously, ice-packed wheels suck. Almost anything is better than doing nothing, except dragging your brakes to put heat in the wheels. Don't do that.
