Hi all, I have seen several threads in the past where people asked about repairing the wax coating on their frame. This may be nice for others to know.

 

I recently took my ride in to have a good once over before my 36 month warranty expired. No real issues with the truck at all. My frame had rust on it, but I didn't think it was that excessive for living in WI. But I asked about it when I was there. To my shock, they volunteered to repair the rust spots and re-coat it under warranty.

 

Here's some before photos of my frame:

I have to do this to my truck.  I only have 3,000 miles on it and no rust yet.  The body shop swears the stuff sticks to the wax.

Have they changed the process in recent years?  My 2017 looks nothing like these pictures or the half painted trucks I have owned in the past.  This looks more like undercoating.

I think the problem is that the stuff just comes off too easily and then the rust gets in and spreads underneath it. I have a 2018 and the thing showed some surface rust as soon as I brought it home...on the bed tubes, on top of the front spring mounts, at four spots where a tech put the thing up in the air on a lift, at various crevices. 

 

I patched some of the bare spots with a rubberized undercoating, on others I used fluid film, and on some others I stripped the coating off, sanded it down and painted it with POR. I feel like it's something that unfortunately I have to keep up with weekly or else it'll get out of control (and it's not even winter yet, this is our dry season).

 

I'm planning on doing two things...I plan on buying some Nox Rust for touch ups, and I plan on doing an undercoating treatment twice a year with either fluid film or NH Oil undercoating. 

 

I know its just "surface rust", it's not the end of the world...might not ever be a serious issue, but I don't want to chance it. I've seen three 2014's that have frames that look so corroded you'd think they were 20 year old trucks (one of them doesn't appear to have any wax coating left on the thing).

There’s a couple of undercoating threads on here you might want to read before you get to crazy with the Fluid Film. Some guys claim it eats the wax.

I was told that, but I haven't found that to be true. And I've seen fluid film treatments on Silverados in my area - including mine - and it didn't damage the wax. From what I've seen it sticks right to it forming another layer/barrier.

I like the idea of letting the dealership repair it. OP thanks for posting the info, if I spot some rust it looks like it will be taken care of, and that is good news. Only problem is my closest dealership is Beaman GMC in downtown Nashville and from past experience with them they will probably write on my repair ticket "Operating as designed No repairs Done" I will have to drive 25 miles to get decent service at Wilson county motors. Yes I am dogging Beaman Service department BECAUSE THEY DESERVE IT AND HAVE EARNED IT. Note: Beaman has an excellent paint department (different building and different management) it is just the service department that is weak. Beaman if you read this and the many other reviews that  I have put out on your poor service department please make some management changes and get yourself back to doing good customer service. I would like to utilize it when needed.

I talked to the dealership about the rust on my truck when I purchased it, it was used with 6,000 miles on it. They would not cover any repairs to the wax/frame under warranty. So it looks like it may or may not be a service that your dealer is even willing to offer.

Yes I agree a lot of the decision to do a warranty repair is initiated by your dealerships service department. If you have a fat lazy service guy that hates his job and just wants to put his hours in without any extra effort like the guys at Beaman you will get told to pound sand on any warranty repairs. Forget any rust repair or other gray area it will not happen there you have to go with a quality / customer oriented dealership service department like Wilson County GMC. Just makes me upset that I have to drive 50 miles round-trip just to get a GM  service department that does not have their head up their arse.

I’ve touched up a few scratches or lift marks with fluid film aerosol. Hopefully this isn’t one of the products that cause the factory wax coating to fall off?

 

Thats great your dealer took care of it and looks like a decent job touching up the problem aeras. 

 

It’s refreshing to hear a positive dealer repair vs “they all do that”, “functions as designed” or “can’t replicate” canned response :-)

To be honest I think the wax coating “falling off”, part of the equation is pretty much impossible to avoid anyway. When it gets old it dries up and falls off. When something scrapes it? It’s exposed. The fluid film, krown, NH oil...all may “soften” it, but unless you soak the heck out of it, I’ve found they don’t make it fall off. If anything they provide a little barrier and suppleness. And then dust sticks to it forming an additional barrier of protection.

    • So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.
    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
