I spent the past two days doing a fairly thorough cleaning of the 2500 since Winter is around the corner and I like to have things squared away before the weather turns. I pressure washed the undercarriage and wheel wells, took a wire brush to and then sprayed some Eastwood Rust Encapsulator black paint on any of the parts beneath (axles, frame, hardware, etc.) that were showing any signs of corrosion or wear on existing finishes, then gave the whole truck a good wash by hand and waxed the body panels afterward. After that I spent some time on the factory front bumper with some touch-up paint filling in any rock chips that have appeared over the past few months. All in the name of keeping corrosion at bay.
It won't stay clean, of course, but I needed a clean truck in order to do the other preventative maintenance. Now I won't feel so bad about getting it dirty again knowing that there are some steps in place to protect what's beneath the dirt.
Hopefully next Spring I can replace the front bumper with a Buckstop unit. It depends on how good business is over the next few months.
