rust prevention what do you use?
 

Hey guys for the empty cavities in our cars what are you useing for rust prevention? For example if you have a good clean door are you spraying anything inside to prevent future rust? I'm thinking you would want something you could spray like a wax that dries to seal the metal. Any home remedies?SmileWavy

I think something that doesn't fully dry is better. Seasonal conditions (temps) will otherwise create cracks and allow moisture in again. Cavity wax or something is what I use, but as I'm in The Netherlands, the brands won't mean anything to you.
