Rusting Frame

Doug Rosewood · August 20, 2017

Has anybody had the thought that maybe wax dipping is the future? You cannot stop nature from creating rust, fords trying with their beer can body's, but sorry shit decays. I had the moment when I noticed surface rust on my 56k truck, but then I realized it's surface rust, I live in the salt belt, and about the only thing I can do is what I did with my 04 and religiously wash it..in the end my 04 had mild rust, but in the 13 years of life it never looked like the titanic

I've seen 2015 F-150's with plenty of rust on the frame. E-coating isn't much better than wax dipping. Well, at least Ford's supplier doesn't do a good job e-coating the frame. I'd love to see frames get epoxy painted. Epoxy paint is excellent.

The frame coating is available straight from the GM supplier, Daubert. On my 2013 Sierra, I spent a few minutes annually with a putty knife, and a can of Dauberts Nox-Rust® X-121B. When I traded the truck a couple of weeks ago, the undercarriage and frame appeared as new. This was after 4 harsh, salty winters, and regular travel on dirt roads. I used Fluid-Film on the floors, and all other painted metal parts. Again, ZERO surface rust, let alone rot. I shall continue to do this with my brand new 2017. The frame coating on this one looks great right out of the gate.

GM used to sell the X-121B through their parts counters under part number 12346501, but it has been discontinued for about 2 years. Here is the link for the Dauberts:

Jeep will be coming out with a galvanized frame. If FCA can do it, why can't GM?

one more to show how caked on it is

Looks like a work vehicle that did a lot of traveling at sites where concrete was being poured, and run through puddles of diluted concrete near the cleanout areas. No rusting, doesn't look like it will hurt anything meybe even gave it a protective coat...I'd leave it ......appears to be working better than the factory applied snot coat.

Found a dealer that was willing to give me 3000 more than I paid for it and got myself a brand new Sierra Denali. ?

Sorry to bump this thread but that is why you don't by the first model year of a redesign.

Has anyone tried CRC Heavy Duty Corrosion Inhibitor on the frame where the factory wax fell off?

Did you apply it right over any rusty spots or did you prep the surface first before applying it?

If your frame wax is intact and it's still nice and soft, I would leave it alone. Just make sure to check on it once or twice a year. I would be willing to bet that if your truck was put on a lift, the bottom edge of the frame will have spots where the lift rubbed the wax off. I would check for rust there, clean off any rust you might find, then re-coat the area with the factory Nox-Rust wax. Also, check the area where the spare tire contacts the frame. The spare tends to rub against the frame and promote rust.

That's what mine looks like under the spare tire after 1 year. Solid rust

What little surface rust was there, I sanded it down to bare, shiny steel, then sprayed the X121B on the bare steel.

You must make sure it is absolutely rust free. Any residual rust will cause poor adhesion with the factory wax. Even oily residue will cause a poor bond. That's why I have not been an advocate for the factory wax. Fluid Film works well for me, but I don't spray my frame with a pressure washer in the winter. I only use one to spray the salt off the body, brakes, etc.

Wow, how many miles and what year is your truck?

I'm not really sure I see the point in any of the applications. All the frame has little holes an cutouts so you can spray the outside all you want to look pretty, but the inside where you can see or spray will be just as rusty as the outside was. Am I off base on that?
