Frame Wax/Undercoating

[nadrojcote]

You're probably right, which is why I'm not holding my breath. I've ordered some rust encapsulator paint and plan on doing my frame sometime in the next couple weeks.

yeah I'm looking into the stuff from GM which is a rubberized type coating. Be careful with paint I read somewhere that can cause the wax to peel off if you coat the wax with it. You're only supposed to treat bare metal spots with any paint. Again I read that somewhere though I do not have first hand experience with any of this. This is the stuff from GM:

The wax was gone a long time ago on my truck. The entire frame is pretty much all orange. Rust encapsulator is supposed to wick moisture away from the rust, so I will probably put it on, then some black paint and then maybe something like the gm spray.

If your wax is gone that bad you should qualify for the proper TSB fix of re-coating the entire frame with that 3 part system that takes like 72 hours to perform. Mine didn't qualify for that the dealer just hit the rust spots with some 3M rubberized coating.

In Canada GM are using a product from Lloyds called Kryptonite

I'm out of bumper to bumper warranty. I don't think that tsb applies to emissions or drive train. Edited April 22, 2015 by projectsummit

Oh I see. Well keep us posted on how it turns out. Good luck!

I already went under and delt with the rust same as I have with all of my vehicles.

 

Hand Wash the unserside and rust paint over anywhere rust is starting.

 

The wax coating is useless I found three sports it just simply fell off of in large chucks.

 

Most of the paint on the rear axel was gone already as well. so painted that as well.

 

Just imagine how far a power coated frame would go GM.

 

I have a 2002 Coleman Camper with a powered coated frame and it has 0 rust on it after 13 years.

Which is good considering it sits outside 365 days a year.

I just came across this : https://www.daubertchemical.com/store/product-list/corrosion-prevention/nox-rust-x-121b

 

That appears to be the product to patch the wax coating if you need to touch it up. I think I'm going to order a can.

 

 

EDIT: Just went ahead and bought a can. It was about $28 with shipping. I'll touch up the rust spots on the frame the next time I get a free weekend to get under there and work on it.

That product used to be available at the dealers for frame touch-up. Don't know if it's still available through GM.

Yeah I thought about calling the parts department and asking but got lazy with how easy it was to just check out and have it shipped haha. It very well could be available at the dealers.

WOW

GM customer care told me to contact a different dealer to look at my truck and fix it.

New dealer ran my VIN and there was already a claim made for the undercoating fix so they won't touch it.

 

This is a pain in the A$$!!

Why not galvanize or powder coat the frames and charge the customer for it? I would gladly pay a little more to know I have something that will last. It pisses me off how they cut corners on stuff like this to save a few bucks. Now ill always have to worry about this thing rusting and having structural issues because of it.

WELL STATED,!!! I'd pay an extra 10% to have top quality materials & corrosion resistant treatments. Galvanize & coat under coat the frames & bodies, Stainless fluid lines, Imron paint in the bed box, etc.

 

i wonder how much of the quality drop is due to forced government environment regulation? Either way, quality chasis & coachwork is almost non existant on most new vehicles, especially by GM.

 

Their procurement & engineering are bottom feeders in this area.

Regarding the wax peeling, it may be due to lubricants used in the manufacturing of the frames. There is a lubricant used during the hydroforming process which allows the steel to conform to the mandrel (mold) without damage. My hunch is that the lubricant was not fully removed when the frame was dipped.

 

I believe GM at one point used Magna Industries to supply their frames.

 

A contrubuting factor to rapid rust growth may be with recycled steel commonly used today and it's high strength requirements (unlike milder, thick frames of the past).

Hit the nail on the head here.. Chances are better then not that it is a supplier issue using a type of lubricant/coolant that is not GM specified and the only way GM could have picked it up was using some kind of FTIR gun to test it for unwanted contaminates before assembly/waxing... Hell I bet GM isn't even doing the wax in house.. So before GM gets a group of people with pitchforks and torches on there front yard give them a chance to render the situation right...
