How do you battle the rust?

I think the industrial version works better on really heavy oxidation.
But I've been happy with the aviation grade.

By using a winter beater with a heater. My nice car sits somewhat parked almost 7 months a year. However, winter's have been shorter and less severe lately so that's a bonus.

I do drive it in the winter, but only after a fresh snowfall before plow trucks get out. Once it's home I spray it off.

>Try and keep up on rust that appears

My winter beater just gets a motor oil coating. Sucks dick when it's time to work on it in a way, but it's better than everything being seized up and rotting away.

>live in a desert
>what little mud there is dries completely in a day

gotta love that 115* and 7% humidity. My car's interior has been bare steel for something like 12 years now and it still hasnt rusted yet.

I've given up. My car is basically rust now besides the body and 90% of the paint. The subframe is cracked in not just one, but TWO places.

I give it through the winter or until it falls apart (whichever comes first), and then I'm buying another car. A better car.
