found this video on a 2013 Siera

it's a ahame GM isn't listening. Ignoring Issues like this reminds me of the old, bloated bureaucracy pre-bankrupsy.

Was the frame on the Jeep painted from the factory?

Here's an article on a common de-icer used in snow belt states, Magnesium Chloride. This stuff is nasty: http://www.washingtonpost.com/local/trafficandcommuting/worse-than-salt-brine-sprayed-on-roads-will-munch-your-car-to-pieces/2015/02/22/b89294e6-b949-11e4-aa05-1ce812b3fdd2_story.html

In my 34 years experience in PA, WV, & OH, a factory painted frame sprayed 1x/yr with Fluid Film is an effective rust inhibitor. The painted frames i've seen usually don't flake off in large swaths like the waxed over bare metal frames. Some of the wax strips seen were 2" long.

Interesting observation. My 2011 AFM 5.3L has 25k on the clock, with current GM upgrades. No oil consumption, but looking into catch can filter from Mann (still closed loop system). I have oil analysis done every oil change, copper was high but down to good levels. Iron still on high side, run nothing but Pennsoil Ultimate Duribility (full synthetic Dexos II approved). may switch to Mobil 1. When the LS motors came out inthe Corvettes, !obil 1 was the oil reccomended by GM.

As long as they don't paint the frames before applying the wax, this will be my LAST GM. It's sad to see local Craigslist ads & salvage yards loaded with parting out GM trucks with bad frames & good sheet metal. Who ever sold GM on this method took them & the customers to the cleaners. Wasted bail out money IMHO.

Interesting read on Magnesiom Chloride effects: http://www.summitdaily.com/article/20070103/NEWS/101030050 http://www.washingtonpost.com/local/trafficandcommuting/worse-than-salt-brine-sprayed-on-roads-will-munch-your-car-to-pieces/2015/02/22/b89294e6-b949-11e4-aa05-1ce812b3fdd2_story.html It's difficult to remove without a pressure washer & soap. It is hell on electrical components, especially wiring. IMHO, that's the job of auto makers to design & build a car that can withstand current road conditions.

Why doesn't GM paint the frames (a good etch epoxy primer) then dip in wax? I think the problem is two fold, residual oil on bare steel frame before wax dip, and wax thickness reduction on sharp edges. Look at the rear wheel well frame area where the round support tube pokes through the frame rail. the edge around the circle is most likely rusted. i check the edges every oil change & touch up as needed. Re the Magnesium Chloride, It's tough to remove.

not sure if i can add much as my 2011 Silverado sits in a garage from November until End of March, butat 23,000 miles the wax dip is holding up ok with a few minor touch ups ((where lift pads removed coating etc.). The truck was made in Indiana (West Bend?). I wonder if the frames used on USA builds is a different supplier than Mexico units? I doubt there will ever be a recall on these frames. The NHTSA investigation into rusting brake lines was dropped agreeing with GM that rusting lines are a 'maintence issue' { ; ) }. Since the government is a major stock holder in GM, it would not be financially good to get GM to do the right thing & reimburse/repair this substandard design, At least Toyota treated the customers well on the early Tundra's! when mine starts rusting, I'll apply Fluid Film the to the frame, then exchange for a toyota. Done with the 3.

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). . When GM switched from a ladder/rivit fram to Hydro Formed frame.

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.
