I am in edmonton, I work for lakewood chev now in service, gonna be able to get the diamond kote tdon at a discounted price while I am at work.

I have sandblasted the most visible area like right at the rim of the coilover mount, sprayed it with matte finishing rust paint from princess auto. To be honest, looks brand new there. I did blast more area, it is pretty much all the way around the outer edge of he frame. Took me two days after work.

Truck will be on a hoist and they will spray diamond kote underbody coating which also adds sound proofing to road noise

 

I think diamond cote is identical to armaguard. Under the body got sprayed as well and looks even better than the frame.

 

Matte black spray paint is actually a good idea. I already have rustguard paint primer as well. Might have to try the matte paint as a good finishing touch in tougher to reach spots I don't want to spray the rubberized coating.

 

Pm me some pics of before and after of your work! Interested to see how it looks.

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

Funny my fluid film'ed frame looks great yet. Wax hasn't peeled off like the some guys swore up and down would happen.

My fluid film was gone after the first winter...it needs done every year just like anything else, it isn't a once and done solution.

There are no permanent solutions outside of epoxy-based paints like POR-15.

No such thing as a once and done solution outside of POR15. Once a year application in your driveway at an average cost for usd$20 is a small price to pay for a clean vehicle. There isn' t truck on the market today that you can just ignore de-icers like road salt or magnesium chloride. Want a rust-free vehicle? Climb under it and do basic maintenace. I used FF once or twice per year and wash my truck maybe three times all winter yet my frame looks immaculate compared to some guys posting in this threaad that have gone back to the dealer for multiple hack-job wax applications.

Agree, but the tone of your original post was like fluid film was the cure...it isn't, and I even had the professional thick bodied version installed. I just got done installing a muffler on my 2012, I have less rust at 80k than some of the photos in this thread off the lot.

 

I think my biggest complaint with the OE coating is that it peels off for lack of adhesion...that's bad surface prep before application.

This is my first post. Ive got a 2015 Silverado crew cab , when I noticed the wax coat peeling in some areas I looked to the forum. I just want to thank the guys who have said to treat the rust on your own. After a couple hours of wire brushing and applying a rust neutralizer I put rustoleum flat black for a finish cote . I'm glad I did it on my own because I would not have been happy if the dealership sprayed undercote and called it good. I had a 1994 Silverado that rusted to the point that when I put it on a lift at my buddy's garage the truck cracked in half like an egg . The previous owner kept undercoating the frame and I assume the rubber just holds the moisture and creates havoc on the frame. Hoping a little elbow grease a couple times a year will keep it strong and looking good.

the frames aren't going to rust through, its an aesthetic issue.

Not sure where you live, but frame rot and rust through is a real issue in the snow/rust belts. I've seen truck buckle in half behind the cab from frame rot...

I just got mine back from having the frame stripped and recoated under the tsb. Happy with it, just hope it lasts longer than the original coat

I noticed mine doing the exact same, the waxy coating was just flaking off and frame rusted worse than what some of you guys are posting.

Just called the dealership and they will not cover this under my warranty.

 

Just wondering for those that had the dealership "fix" this issue what it costs?

I haven't sprayed mine with oil in two years...2012, 90k miles, Pennsylvania rust belt...that pict is from today. If you want them to last, take matters into your own hands. Cost me less than $20 for the sprayer, I use drain oil from the trans, power steering, and differentials. There are also guys that will oil undercoat locally for about $50.

 

I tried fluid film, it washed off in a lot of spots within one winter. The wax coat shriveled up and peeled off in a lot of spots after the fluid film was sprayed.

 

I have owned vehicles that were Ziebart coated, that worked ok, but eventually that caused rust since they only coat certain parts with wax, the rest is a traditional undercoat that traps water.

 

I've used QuakerCoat by Quakerstate, it did alright but is pretty thick and I don't even know if it's produced anymore.

 

The only thing I have found that works for me is oil undercoating. Once it traps some dirt/dust, it builds a body that remains wet...that becomes your undercoating. It's not pretty, it's not clear, and it's obviously not for everyone...I don't have this truck to show, I have it to work.

 

Again, just my experience. YMMV.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      Towing In Loose Gravel

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
