CryoMode industrial ceramic undercoating applied

Did they coat inside the frame through the access holes?

Yes. I believe that’s the standard practice when you get their under coatings.

@Formidable Thank you for this thread post! I am a recent new 4Runner owner and was looking into undercoating in WA State and came across this thread! I actually reached out to this shop, and they told me about you haha!

How is this holding up so far?
Still really happy with it?

They quoted me $1800 whereas I got a quote from LineX for $450 plus tax. Of course, it's a completely different process, quality, and service. It's such a massive price difference I wonder if it's worth it.

No problem. Main thing is that you do something. Whether that’s CryoMode or linex ultimately it’s preventative maintenance. I think the difference in cost comes down to the prep work involved. CryoMode will remove the wheels and skid plates to get into every nook and cranny. They spray the ceramic coating inside and out of the frame. It’s as extensive as it gets and part of what you pay for is peace of mind. End of January is nearing and February tends to be the most severe. After this winter I will put the 4runner on the lift and take some photos of the undercarriage. Will post those pics on this forum to follow up along with some shots to demonstrate how the hydrophobicity is holding up.

Either way, good on you for considering undercarriage protection. The frame rust posts for the 2024 Tacoma are starting to pop up (same frame). This is a known Toyota issue that goes back generations.

I appreciate the reply and looking forward to the follow up pics! Yeah, I could not imagine dealing with rust on the frame for the price of these 4Runners.

The sad part is Toyota knows this is an issue. There was a class action lawsuit a decade or so ago and a massive recall (where Toyota replaced the frames). Wife’s 2015 Acura MDX and now 2021 MDX both have zero rust issues driving through the same salted winter crap. Even the undercarriage of my 2021 Durango hellcat is fine. Why Toyota doesn’t beef up the undercarriage protection particularly on their off-road lines is beyond me. Especially at this price point.

@Formidable , thanks for this thread, and I've read some of your past posts as well on the subject of undercoating - very knowlegable!

I spoke with a good shop near me and they offer a Cosmoline (5 years) undercoating, Dinitrol based undercoating (7 years), and a FluidFilm (1 year) option.

Initially, my intention was to go for the FluidFilm + annual reapplications, but after seeing the Dinitrol application in-person and speaking with the shopowner for quite some time, I am now leaning towards spending the extra money and going with the 7 year Dinitrol solution.

I live on an island and get blasted more with ocean salt spray than anything else. Although I haven't yet (and probably won't for the next year), I do intend to use my truck on the beach for fishing, so it's going to sit a few feet from the ocean and be well exposed to sand and salt spray. What do you think - go with the Dinitrol or would the waxy FluidFilm be a better option? If the former, is there anything else I should know or ask the shop on how they apply it?

My truck's at 300 miles and want to get her protected asap

Thanks in advance!

Any of the three options are fine. It will depend on your budget and how often you plan on reapplying. Honestly fluid film works great! So does wool wax. The issue is when you forget to reapply. Sometimes the weather changes on fairly short notice in Seattle. Back in 2019, on a rainy morning in Feb it started snowing mid day. By the time I was done with work they had salted the roads where I live and continued to salt for a week due to the inclement weather. I had an older 2008 4runner at the time and the front diff support, radiator support, and the bolt holes holding up the front skid plate were fairly corroded. Wire wheeled everything down and applied POR15 metal treatment, rust inhibitor and epoxy (great product btw). I just forgot to apply fluid film in Autumn and the winter seemed mild at first so skip one year what’s the harm? I won’t be caught in that same situation going forward. This reminds me to get some pics posted of my 2025 undercarriage. It honestly looks the same and the coating seems to be holding up well.
