2027 GM Fullsize - Finally E-Coated

[MrkofXcellence]

Well, just after I buy a 2026, they move to E-Coating in 2027. I just don't know what it would be like to work under a truck without getting all smudged up. Seems like it would make you soft after a while. All jokes aside, hopefully this helps with the frame rust some people experience. Do current F150 frames fare better?

It sounds like it should hold up better. I'd probably apply my favorite rustproofing compound over it if it were mine and I planned on keeping it a long time.

The GMT360 platform was e-coated as are all the midsize trucks. They changed the wax at some point as the GMT800s never really seemed that bad to work on (harder wax) our 16s, 18, 22 and 26s may as well just have fluid film on it as I can nearly change race just from an oil change.

That being said we have GM trucks in service up from the 90s to present and the frames were never an issue. All coatings to present seem effective enough.

I don't believe any manufacturer can justify the amount of undercoating needed to survive winters here. Additional coating should be applied if you want to keep a daily driver solid.

My 2004 GMT800 has been through 21 northern Illinois winters, and the frame is just now starting to show surface rust.

Considering the way that the corrupt Illinois Department of Transportation applies salt to our roads, I do not see how a painted frame would have fared any better, than the "wax" coating.

3 Adirondack winters on my '23 and the wax is coming off frame holes and bracket edges. The touch ups are ongoing.
We'll see how the new coating stands up in NYS where they treat the roads with salt and sand.

The wax coating wasn’t bad, what was bad is that GM put that wax coating on a bare metal frame. Had the frame been painted and the coated with wax, it would not be an issue.

I tried to find out if the HD trucks were also changing but I havent heard back yet.

I don't think the HDs are getting refreshed this year, so I'd say no.

F150 frames fare much better up here in upper michigan. After 1 winter up here a GM frame is 80% surface rust id estimate. Ford and Ram are 99.5% paint after 1 winter and probably 95% paint after 10 winters. Ive heard of 5 people needing frame patches on 2014 and 15 silverados up here, not 1 ford or ram from that era yet.

They are. They have built a couple of runs of pilots and just recently a preliminary run of saleable units. (which will have to go through extra validation testing) The refresh will be similar to the 1500's in that its slight cosmetic but some big changes in mechanical, interior and electronic architecture as well as the new Duramax. 27 Production will start some time in the fall.

I did see a "de" camouflaged 1500 yesterday heading North from the Milford proving grounds after quitting time. It still had all of the test ports on the exhaust and some poorly removed wraps, especially on the wheels. They arent trying to hide them any more.

I Fluid film every new vehicle I get and pay extra attention to the frame on the trucks. My experience is that the wax stays a little softer with the FF on it and can be easily touched up. Since the application gun has wands I can get into the boxed areas of the frame easier. Typically the frames I see breaking are on trucks that had no extra rustproofing or cleaning measures over their lifespan. Lots of 2008 to 2013's that werent ever cleaned other than the monthly automatic car wash. Before I found fluid film I was using chassis grease on my frames.

News to me. Last I heard from a... friend I guess I'll call him... The HDs were probably happening for 28. This was like last year when everyone thought the 26s would get refreshed though. Guess we'll see.

Glad GM did this, great news.

Next GM needs to follow some of the European automakers and quite using cheap steel pipe for brake pipes, and change the material to copper-nickel.

I do the same. Rust proofing should be done regardless but the ram and ford coating does produce a longer lasting product

Our new Yukon appears to have a fully painted frame, thankfully. Not that we really need it down here but I have some fluid film I will add when I get a chance since we may use it to put the boat in salt water and we live near the coast.
