Rust Proofing

I rustproof all my vehicles, including my Edge and my girlfriend's MKX. It's an oil-based product which when done properly goes into every nook and cranny and stays there, diminishing by a lot the risk of rust forming in hard to reach spots. They do the whole undercarriage,floor, inside crossmembers, etc, also inside the doors and tailgate (especially the bottom where dampness usually stays). I've always got great results with that kind of rustproofing and I don't understand which are the "problems" which RJG" is referring to... :headscratch:

The steel has to be completely clean, dry & bonded properly. Problems come from trapping moisture between the coating and the metal. Older coatings split and chip, allowing moisture to migrate between the coating and become trapped there. I had one of my cars undercoated professionally. They cleaned the bottom with steam, allowed to dry for couple of hours then the coating. Had to take it back every year for touchup. Still rusted in spots they could reach.

Like in my previous topic, if you don't wash your door lips, your doors are going to rusty quickly. The bottom of doors fold around the bottom of car,getting a lot of salt,mud,etc. On bottom edge of car. I was disappointed when I seen how thin the metal is. Every time I wash vehicle, I wipe down inside door panels & trunk/hatch, & that's when I noticed problem.

Dirt does accumulate at the bottom of the doors on mine too but like you, I wash it off and wipe it dry every time I wash the car I guess it pays off because I have a 2016 (2 years old now) live in Canada and don't have a single spot of rust anywhere on my vehicle. Rust will form if you allow the dirt to accumulate get moist and leave it there…but nothing beats prevention like a yearly spraying with an oil-based antirust product.
