Frame Wax/Undercoating

Clocked92 · January 6, 2016

My dealer phoned me the other day and told me they have a few trucks lined up to get the frame fixed. Mine is 3rd in line. The first one they are doing is the General Manager's truck. I'm assuming they will try to do the best job they can on his truck and then they can do mine.

I'd really like to see before and after pics of the managers truck before I give them my truck.

I have a 2014 Silverado that just had the tsb done. The overall process was alright overall. I will say that I am alittle OCD about my vehicles so just throwing it out there lol. They did not hassle taking on the job at all which was nice, but I do have some complaints of the overall job done. They had the truck for I believe 3 total days. They did scrape off all of the wax coating and applied Norton rubberized undercoating to the whole frame. I do wish they removed the bed and rear bumper to do the job correctly in my opinion but they didn't. There are numerous spots of decent overspray which I am not happy about but the frame overall looks better than it was. Hope this kinda helps.... I will try to post some pictures at a later date.

I tried the Fluid Film on my frame back in November. I sprayed in on the part of the frame you can easily see in the rear wheel well. It was very tacky going on which is good, however I put my finger on it just to feel it and as I wipe it my frame coating came right with me. I had it on for about 3 weeks and washed my truck twice at the quarter car wash and also drove in a few rainstorms. There was some additional spots where the coating was kinda running off when it was all said and done.

I ended up having my entire truck Ziebarted. I did the full rust proofing. I'm satisfied, but a little unhappy with the quality (overspray). I spent a few hours with wax and tar remover getting the overspray off my wheels and paint. I opened the hood recently to empty my catch can and noticed that a lot of stuff under the hood has some over spray on it too, such as the Brake Fluid container, its very obvious there since that is a clear container. I noticed my mud flaps have some overspray too, no idea what I'll do to get that off yet. It's so minor though that no one would ever notice any of this except super anal detailers like myself. We'll see how this Ziebart plays out... may be a great investment or a big mistake, time will tell. I gotta go back once a year to keep the warranty.

Oh, and the interior of the truck is even quieter now.

I do plan on using Fluid Film still on my wheels and also the trailer hitch. I haven't sprayed either yet because of laziness. Thankfully the winter has been super mild here in SE MI, which is also bad because my snowmobile is just sitting.... :-(

Wax undercoating

Tpalavra22 · January 7, 2016

Yes I've noticed my 2015 Silverado has a slight issue with the undercarriage coating, seems like either it wasn't applied right in some areas or those areas may not have been prepped correctly?? I'm an aircraft mechanic and we use this product called ardox AV8 and AV40, it's a tough corrosion proof coating which you can buy online and we use it to protect our planes from corrosion, I'm going to coat the whole underneath of my truck this weekend in hopes that it'll stop from a future rot out.. I'm also open to anyone else's ideas or methods... Winters coming lol

This is a pretty overblown claim that you've read. I've applied FF 3 times since I bought this truck and have had zero issues with it "taking the wax right off" like some swear it will. I'd be happy to provide more pictures. After coating the wax, it became slightly softer and seems to almost self-heal now, but still sticks to the frame just fine. The last thing you want is the factory wax to become hard. Hard wax likes to become brittle and either peel away frome the frame like we've seen in this thread, or worse, wick water and road salt between it and the steel frame, rotting the steel while looking like it's still protected by the coating.

I was just under my truck last week and found large areas under the bed that I missed while applying the FF and those areas look just like COP TZR's frame. The wax is flaking away and peeling at the edges of the cross members. So now I have to scrape all the wax off, apply rust converter, paint it, and hit it with FF. Why would I apply the same shitty wax that failed to do it's job the first time, not only on my truck but every guy that's been to this thread for help. That's just stupidity. It's not like the K2XX trucks suddenly have an issue with wax peeling off the frame that GMT900 trucks didn't have. Look under any GMT900 truck in the Midwest or Northeast and it'll be pretty obvious.

Im starting to think the same. I did two test spots in my wheel well. My rusting is still very minor so not ready to strip and paint. The two spots I sprayed conservatively have darkened in color from the oil(so harder to see which is a nice plus), and so far not flaked anymore from that area. The wax just at the edge is only slightly softer than the dry parts of the wax. So far so good, but Ill keep my eye on them.

You pressure washed the frame? Yeah bad idea. With or without the FF, the wax is going to get blasted off.

To anyone that uses FF over the factory wax, you don't need to pressure wash the frame off with it applied. I rinse the frame once a winter on average using a low pressure spray nozzle.

Some 'undercarriage' items are not coated, some are painted (or e coated) some are waxed.

Well I picked up my truck today from the dealer after the TSB fix. Looks like they did a good job stripping and cleaning the frame. They applied the appropriate inhibitors and then the finishing coating. They also under coated the whole works after they were done on their dime. Very clean and no overspray whatsoever. We'll see how long it lasts.

Those "circles" on the frame by the rear wheels are starting to rust on my 2015 with a build date of 8/2015. Truck is one month old with 1200 miles. It isn't very bad yet but when does it get bad enough to take it in?

Jordan18 · January 11, 2016

I had a product called "Armaguard" done on my frame and I fluid filmed the rest. Basically a rubberized bed liner type coating but slightly softer.

Attached pictures.

So my dealer has never done this job before. Should I take it to one that has? My dealer is saying that the bed will have to come off to reapply this and they wont give me a demo either. This sucks because I even work at the dealership. They keep acting like they do not have any time for me. I guess I will end up taking it to our main competitor, because they will give me a truck to drive while mine is in there.

MWZad · January 26, 2016

I would say I agree with you about the loaner but I really wouldn't complain about taking the bed off. To me, I think it is the only way the job can be done correctly but maybe that's just me.

Yeah I see that but it just scares me because they have never done the job. I feel more comfortable taking it to Everette
