Step 1: General maintenance
b. Wax your car once every four months.
c. Keep the inside clean as well, being sure to clean up after any spills which can start rust from the inside.
Step 2: Take extra care around salt
b. Clean the underside of your car and your wheel wells when filthy or at least once a week during the winter when salt is out.
c. If your car is seriously at risk for rust because of regularly exposure to salt, etc. you can clean it and then spray it with a lubricant appropriate for cars (we recommend Jig-a-loo, of course!) or even paint it with a proper coating for the surface (this should be done by a professional).
Step 3: Rust Coating!
b. Key is to keep metal surfaces dry- whether you wipe them off after use, or protect them with paint, lacquer, lubricant or wax.
c. If you are going to spray your car with anything flammable. make sure the engine is cold and give it some time for the vapors to clear up before you fire it up again. Try to avoid spraying on your exhaust or mufflers so they don't get to smelly when hot.
