Didn't know that Fluid Film will soften the wax. That said, it's not petroleum based and therefore is safe to use around rubber and plastics. It's great for places you can't reach like inside the frame, inside doors, etc. I find the wax chips easily ... probably even more so in winter.

I heard that Fluid Film is still best, to use even tho it makes the wax soft, just have to re-apply it yearly. Its bad when the wax gets hard cause then it chips off...

Chevy /GM wax is really only there for assembly of the trucks to keep the frames nice, and is not intended to last more then a year off the assembly line. (Nielsen Chevy , mechanic told me this information...)

Based on that link, it looks like Ford is using the same crap?

 

I use fluid film on my boat and waverunners, works great until I have work on it... which is extremely rare but it keeps the rust off everything, haven't tried it on with our wax coating on our trucks.

 

I my last Denali the factory wax was so dry it would fall in pieces in my driveway, rust to primer paint, wait to dry then add the 3M under body coating and its held up grade for the past 2 years but I am TX.

 

like the others above stated, GM is using https://www.daubertchemical.com/

the Daubert stuff is the brand of wax on the frame?

 

Yes sir, it should be the same soft black wax coating but it will apply thinner from the can vs dipped at the factory, I like it but it does come off easy, get rust to primer paint, then wax it.

 

Based on that link, it looks like Ford is using the same crap?

 

 

same company but different product

 

 

GM = Nox-Rust®X121B ------------------------------------------ GM part#12346501 not a good part number anymore

GM Technical Service Bulletins PI-0564D and 14002

Nox-Rust® X-121B (also known as "Nox-Rust® X-121 Black") dries to a firm wax-like film that will repel water, self-heal, and remain flexible at low temperatures. Can be easily applied using low-pressure airless equipment.

 

Ford = 7703-W (Ford did use x121b in the past)

Ford Technical Service Bulletins 15S14 and 14S22

A low color, translucent rustproofing compound with a thin gel, but low viscosity. This allows for film builds on vertical surfaces and for seam penetrations (capillary action) into areas with metal-to-metal overlap. The resulting film is wax-like in nature and will repel water, self-heal and remain flexible at low temperatures. Dry time is 4 hours to touch and overnight for full cure

wheres the best place you guys have been finding the dauber frame wax stuff. looks like it comes in a 1 quart can to brush on.

I just ordered a case of 12 cans off the Daubert website "$131ish shipped & taxed", I will let you know when I get it, I need to touch up some spots of when rubbed off some areas when I added my GM Borla exhaust and front off road plates.

jamoka3, that's not the same product. its a Daubert product for sure but its 3100 not X121B

 

3100 = The dry film is firm, amber/translucent and when applied to the recommended dry film thickness, will protect ferrous and non-ferrous metals in protected or unprotected storage. It can be handled after 3-6 hours, and sets up in 12-24 hours. Nox-Rust 3100 can be removed

From my understanding Fluid Film is simply wool wax, but since it comes in varying viscosities; it likely has a solvent in it.

 

It worked well in the doors and the body on my truck, but caused sheets of the factory coating to shrivel and peel off to bare metal.

 

I think all the the issues with the GM coating is surface prep...something on the frame during application is preventing proper adhesion.

If someone uses the daubert stuff sometime soon let me know, I wanna hear from a few people before I get some maybe.

 

This is the product you want, the aerosol spray it has a little more gloss look. The factory machines that carry the frame down the assembly line will have 4 spots of frame that are un coated b/c the machine rubbed it off, plus anything thing else during assembly. let me see if can grab some pics.
