Frame wax coating repaired under warranty

Do you just apply it over the areas or do you need to prep it first?

That depends.  If you have the problem described in the TSB, (areas of the wax not sticking to the chassis) GM recommends prepping the surface first.  I just apply the coating directly to the frame (after cleaning) for repairing small areas where the coating has rubbed off, ect..

When I bought my '17 last June, I did something that I normally wouldn't do; I paid a bunch of $$ for the undercoating.....('Trucoat'-...LOL). GM dealers here in Ontario sell an undercoating that goes on thick and only semi-dries. It won't come off from driving conditions like many other products do. It goes on right over the wax and doesn't cause any problems with it.


I had to get the installer to do it twice, because they did a poor job the first time. They didn't do much better the 2nd time & I had to show them how to do it properly....... Frustrating..

Later, I also bought some amber body oil & some black gel undercoat from another supplier & did all the interior panels, etc. (that the undercoat installer didn't do properly either).

I also sprayed the black gel over the 'undercoat' to keep it from drying out & also inside all the frame rails, suspension, axles, etc. 

During the winter I try to wash the undercarriage every month or so & again in the spring after the snow melts.


This spring I asked the dealer if I could buy some of the undercoating from them to do touch-ups etc. They sold me a can of it, which goes on a schutz gun. They only charged me $15.00 for the can. I already had a schutz gun at home, so no problem applying it. 
I went over everything this spring again to touch up etc.
.

After a year, the whole undercarriage still looks like new.

I'll just buy more of the 'Trucoat' from the dealer for future touch-ups.

 

I figure if I can keep it looking like that for 5-6 years, with a few hours of work each year, the truck will be worth several $'000 more to sell or trade when the time comes. Plus, it looks nice when everything is black and clean in the wheel wells etc. & also is a lot nicer to work on when everything isn't all rusty.

Why aren't these frames electrodipped and painted? Isn't this 2018?

2017 silverado with the same frame coating issues everyone has been talking about. I'll post photos a bit later.

I just had my frame coating mostly repaired at my local dealer. They gave me a new chevy cruise to drive. I gave them fair warning that I am a bit picky and that I have taken photos and will be taking photos of the work.. 

I ended up refusing pick up twice because portions of the frame were either missed or just sprayed over the existing flaking material. At the second refusal I noticed that both catalitic converters and portions of exhaust had been hit with overspray as well as the driveshaft, side steps, and rear door... I told them they needed to do better and will be cleaning it up...

The day I picked up the truck I found that I still had cracked frame coating with could see rust visible at the rear bed tube, oh  and the exhaust still had overspray on it.

I was told the shop had twice the amount of time into the truck as the TSB allowed and that they can't do any better.

I was told the exhaust was cleaned the best they could do, "those aren't cataliics copnverters" (without them even looking at it and I'm a mechanic! lol), that any smell would burn off in no time and not to worry it wont catch fire

I asked to see the materials they used so that I could do the rest of the repair myself. The shop tech came back and gave me what was left of the three cans about half full of the stuff.

Three days later the truck still smells to the point I have to roll every window down when I stop a long light. (It was 35 degrees out this morning)

I've contacted the body shop this morning to give them opportunity to resolve the issue. After that fun conversation... I called GM corp and opened a claim with them. 

 

thoughts?
