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?

It is important to flush out the frame with a garden hose at least once a year to prevent accumulation of dirt and debris that can lead to rot inside the frame.

Ok, I am new to this site but as a GM tech who has been pushed too far, its time the truth came out! I know for a fact in the northeast, there is a service bulletin #PI056E: and its titled wax coating

That's not acceptable! Looks like it was done by a blind man. I'd be back there demanding to know why they had the truck for 3 days and that's all they accomplished. I sincerely doubt it's GM's fault,

Well, now you see the GM manufacturing trend for these trucks. The idea is to produce a comfortable vehicle with a car like ride, silent interior, and loaded with gadgets. This is bound to impress t

Damn mine looks the same as yours. Are you planning on doing anything? I've considered taking a wire wheel on a drill to the frame under the truck and then painting with POR-15 but I dunno if it's worth the hassle.

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
The wax coat frame is a grand idea, and I bet it would work just fine...GM seems to have an adhesion issue, which is a preparation problem and not an issue with the coating itself.

No boat, the truck was driven by a salesman at the dealer before I bought it so I’m guessing it just got driven in salt and never washed.

If it was a demonstrator, they get washed multiple times a week...

yeah but how many of those car washes have undercarriage wash things as well?  So much salt and chemicals get up under the truck and can eat at things that way.

If it was the dealer I worked at, it got hand washed nearly every day.

I have a 17 sierra, just looked the other day, slight spot of rust where the jack/hoist touches the frame.  Seems anywhere the wax coating is disturbed will rust very quickly. I had a 2015 Silverado, got a Krown oil undercoating done. never had any rust for the 2 years I owned it even with winter road salt.  I plan to get my new truck done soon.

 

Like already stated, it helps to regularly spray off the undercarriage especially if you live in an area that uses road salt. Highly recommend getting a rust proofing spray done.  (not fluid film though as from what I have heard will melt the wax off all together)

Just bought 4 cans of Dauberts Nox-Rustemoji768.png X-121B.

My frame has very little of the wax left on it.

Truck has always been in NC. 

Going to do it myself.

Just purchased a 2018 silverado 2500 hd a month ago and now noticing some surface rust on the frame in a few spots. Factory wax is not as bad as the 2013 gmc sierra 1500 I purchased new. I wanted to get the line-x undercoating but wasn't 100% sold and did not want to void the factory rust warranty, if that really matters. What would be the best course of action to stop this mild surface rust dead in its tracks?

Forget undercoating......just spray any rust areas with Rust-Oleum RUST REFORMER comes in a spray can. Instantly converts rust to a protected surface....chemically converts the iron oxide to a rustproof compound with a flat black finish matching the existing frame coating. Sprayed the few rusted frame contact areas 2 Winters ago and still good.

      I am sure that was quite the pass experience and not a great place to experience during the winter when the conditions are not good. I've seen video of that pass and also more detailed information and pictures about the wrecks at that one hair pin turn where tractor trailers have flown right off the cliff and I am sure from all the warning signs that you know the exact curve that was !. After all there is a reason why a song was made about Wolf Creek Pass !. By the way and I didn't realize this either when I bought my truck as its nothing I even thought of that would be programmed into the cruise control and this occurs in either the basic or the more advanced cruise that controls your distance behind a vehicle and that is the brakes going down a hill are being applied as soon as the vehicle goes a certain speed over the set cruise speed. While it certainly does force downshifts in the transmission as you found out with cruise on while going down hill, its also dragging the brakes as needed to keep the speed controlled to what the cruise was set to. For me, I find that unsettling simply because I have no concept then as to how MUCH brake input is being used a and just how hot are those brakes getting and the wear factor as well. I can see that system getting a person into trouble on long mountain grades while pulling a trailer as it would not only be standing on the brakes of the pickup without any driver input, it would also be automatically applying the trailer brakes and it could cause a run away unit by overheating the brakes. Its one thing on a shorter hill and if the driver allows it to do its thing but on a long mountain grade is where things could get so out of hand. As someone a while back on this forum said, they had someone following them at night I believe on a down grade and had the cruise set and the person behind them could see the brake lights being energized all the way down the hill. I figured when I saw your comment that you didn't know and would have no way of knowing that your truck was applying the brakes and that you would and rightfully so assume you only used the brakes when you pressed on the pedal to slow down more than the cruise set speed for the slower sharp curves. So its good knowledge to know this about the newer GM trucks, certainly when doing any descending on long mountain grades. In the future try kicking off the cruise and use the the manual mode on a pass to see what that is like as I know myself when I first experienced it I thought no way can this engine be holding me back this well and tried the same hill in manual mode and sure enough the engine was revving way up and still could not hold the trucks speed down like it could in cruise mode.    Fuel mileage, that is where a really low sleek type of car can do better at higher speeds, certainly it starts sucking fuel too but a tall pickup is pushing massive amounts of air and also allowing a lot more air under it and the tow mirrors as in elephant ears pushing through the wind  as well. Driving like grandpa is about as good as one can do when driving one of these if trying to get the best fuel economy they can. I bet these trucks would get the best mileage they can if driven on a freeway in Florida if not busy traffic at a sedate speed and that sea level elevation without hills, vastly different then Colorado !.
