PBlaster "Corrosion Stop" is now officially in my cabinet, and I spray it on all exposed under-car exposed parts, boltheads, nuts, bolt holes,brake line connections, anything that will rust, except the exhaust pipes themselves. I spray a little on the exhaust nuts, and it seems to burn down to a protective layer.

 

I think it's basically grease disolved in acetone, but it leaves a pretty dry surface after a couple days.

 

They still use mountains of salt here in Chicago. It's pretty flat and just absorbs into the soil. In 50 years nothing will grow here at all. As it is, we have to bring in topsoil to grow anything besides weeds.

 

Also, I at least loosen and retighten caliper bolts, if not remove and antisieze them. I did brakes and struts recently.

 

What do you do for winter preparation?

I usually spray some undercoat in my wheel wells (and under the car)

 

A good wash/wax is usually in order.

 

Check brakes, hoses, and fluid levels. I also like the "deep" floor mats that hold lots of slush from my boots (beats frozen carpet)

 

A winter tool kit (shovel, carpet, gravel etc) as well as some warm clothing and MRE's for food/something to start a fire if need be.

 

Extra oil, coolant, 90w gear oil etc (those I carry all the time though)

I've been using a product called Rust Bullet. It not only stops any rust in its tracks, but also, it creates a tough, durable coating.

I am told it is so effective, it is used on Navy ships.

It is some work to: Put the car on ramps, and basically paint the underside of the car, however, so far the undercarriage shows no new rust whatsoever.

Additionally I bought the chemical Dryer additive- this allows for much faster drying time.

Here in eastern Canada we spray our cars with a mixture of hot oil and wax. The wax stops it from dripping too much.

To do it properly, you need to get it in between the panels too,(inside the doors, tailgate, rockerpanels etc...), in addition to underneath and around the engine compartement.
