Rust is ultimately inevitable but we all want to prevent it as much as possible. Obviously the best rust prevention is to keep your vehicle clean. But, are there key areas we can focus on to deter rust from developing prematurely?

Here is one area that is easy to identify as it is likely seen during every entry/exit of the vehicle. This is also an area that is likely not well cleaned during a “normal wash” or even a “thorough under carriage wash”. It requires special attention with door open.

Is there something to treat this area with to keep the seam from rotting from the inside out?






Here is another area of potential rust problems and a possible preventative action.







What other areas have you all found and what preventive actions can you suggest?

I've been using Fluid-Film and I like it so far. Theres a local place here that does a complete coating of the undercarriage. I've only noticed one spot that was getting surface rust and that is right where the bed meets the cab on the bottom corners (on the cab). I'll take a picture tomorrow morning so it's more clear.

Also available on Amazon for DIY.

It's non-toxic and doesnt drip.

The way to stop the rust in your door channels is get a can of white grease spray. Insert extension nozzle into the opening at the end of the door and spray. You can then park on a slight forward angle. Overnight or maybe sooner you will see the grease coming out of the opening at the hinge end. This is a process that many body shops use, especially on their vehicles. Water gets into the channels no matter what you do but this should help a lot. If you could find undercoating that has a small nozzle to fit into opening that would work also.
