HAHAHA I forgot about that

 

Yes, Ziebart was the go to in the coastal areas along the Gulf of Mexico and Atlantic. We lived close enough to the beach that I would get surfspray on my bedroom windows growing up. And our anodized AL house windows would powder and flake away after a decade or two, so, so much for Aluminum not rusting. The Ziebart coating we had installed on new vehicles was this THICK black, waxy, oily, asphalty substance that would stick on forever. I disliked getting the stuff on my hands when working under cars and trucks as a kid, but it sure stayed put and protected from rust. Park your vehicle on the street for the first week of treatment, as some if it drips off until it sort of cures....

 

2021 F350 DRW 6.7L with 8 foot bed. I live in the midwest and have for more than 6 decades. Owned plenty of Fords and rust - especially on frames has never been an issue. Currently winter in the Keys 5 - 6 months and launch my boat weekly in saltwater and drive down flooded roads with salt water after heavy rains. Only thing that has some surface rust are tie downs for the truck camper from a 3rd party Torklift.

 

Haha, I live in the snowbelt of AZ, and my dang gum Torklift truck camper mounts are also rusting on my 2018 F350

 

I would be highly skeptical of Ziebart.

I prefer Krown to Fluid Film - it creeps better and doesn't stink. Easy DIY unless you want to get inside doors & body panels, which is not necessary with an aluminum truck IMO.

 

They salt the roads here 6-8 months of the year, depending on the winter, and they seem to do it a lot more these days.

I’ve experimented and used a lot of various products, from expensive in drums to what ever is on sale in a spray can at tractor supply. my experience is a light inhibiting oil to creep into seems, it really doesn’t matter which. And woolwax over top of that, and over all inside and out, once it’s had a chance to creep in. Woolwax doesn’t wash off like lighter coatings such as Krown, or fluid film, etc etc.

To make the mess worse, I drive down dusty gravel roads, which coats the oil in a nice layer dust and dirt which helps the oils stay in place.

Reapply as necessary. Clean off as much rust as you can, and apply over top.

Steel rusts, aluminum corrodes. Either way, it is good to coat both. Aerospace has special corrosion treatment and inspection programs for just that reason.

It’s a Royal mess to work in after, but seems to be working the best I’ve tried so far.

A lot of it also depends on the shop applying and what their process is. Some are 30-60 minute shops, which apply with everything wet from power washing, and somewhat clean. A good shop will have the vehicle for two days, one to clean, dry overnight with heat and ventilation on, and the next day to apply.

Eventually, no matter what I’ve done, unfortunately things do rust. Oiling did save my ‘96 and I was able to rebuild it, it no longer sees salt.

Thats my experience, good luck with it.

 

Hey Augam, now that's reassuring to hear-after almost 70 years I've never lived in a place that salts the road before- Hey old dog and new tricks here-LOL

Thanks I'll give them a call

 

I run NH Oil every fall, probably doing my truck next weekend, as well as my enclosed trailer. It's nice that it creeps, and you get a nice thick layer where you don't get heavy road wash. I basically touch up the heavy wash areas yearly.

 

I just did a test spray of Fluid Film 3 days ago and its still wet, does it ever dry? Or just wash off from the slush and rain? How good iyo is Fluid Film?

 

Fluid film never dries but It will eventually wash off. I've been using it for 12yrs and it works great.

 

just becomes a film unless there is a ton of rain, like constant and even then it is still there.

A coating lasts me all winter, with lots of rain, snow and ice and that stupid salt they use on the roads.

 

Up here it's the calcium and the sand that really does in the wax based and thinner oil undercoatings. My brother had one of the black wax based undercoatings on his 18 done when he bought it new, didn't last the winter. I bought a used '17 with 30k miles, used it for 3 winters with NHOIL and at the end of 3 years my truck had no rust, his was pretty covered in the axles/springs/suspension parts. Mine was like new. And I used mine to plow.

Admittedly my current truck is only 2.5 years old, but I'm almost up to 40k miles and I know if I go scrape the frame with my finger there is definitely oil coating it still.

 

I think GM is known for just wax on the frames. it does not work.
