Rust Proof Planning ('23 GX)
Hey All, About to rust proof my frame in the '23 GX. Watching the Care Care Nut, he only does the frame, axles and break lines. He avoids doing everything else as far as I am aware and mentions in his review video that everything it is not needed (rockers, belly pans, doors, etc, etc.). I know there are plenty of older Toyota's that have rusted panels, around wheel wells etc. I'm just double thinking this. I do live in Toronto (rust belt). I think he doesn't spray everything because the entire bottom of the truck after a few years looks caked with undercoating. What your thoughts and experience on this? I did search Rust in the forum, but wasn't too successful in the GX forum.

I'm in Wisconsin and it's not very common to see rust on Lexus body panels, like actually pretty rare vs everything else on the road. Whatever formula they've found...it works and they should never stop. I think the care car nut doesn't go into doors and other areas because that's where the real work is, pulling panels and spraying in the cavities. From my research a compressor and spray gun with appropriate attachments are the key to coating the inside of those cavities with a light mist. My concern with doors specifically would be the coating weeping out the drain holes and causing a mess on the running boards/etc.
There are diy kits that don't require a compressor and dedicated gun for cavities, and those might be worth a shot. Something like this is what I plan to use for inside the frame cavities and similar areas under the GX.

Cool, Thanks for response. I bought the woolwax kit with pro gun and using my buddies huge compressor and going to regulate the the recommended pressure indicated by woolwax. Comes with two extensions, one direct spray and another 360deg. For now I'm just planning to do the same and care care nut. I think key to preventing rust in panels is to wash your car and make sure no buildup of sand etc. that could collect in rockers near the wheels.

Focus on the Frame ... and not just exterior protection ... frames typically rust from the inside out ... so take to a reputable shop that have the wands necessary to coat the inside of the frame.
Research 4-Runner forums on this subject ... the GX is essentially a glorified 4-Runner ... the underside is virtually identical from a mechanical standpoint.
You are doing the right thing ... research the class action suits on frame rust for the Tacoma, 4-Runner, FJ Cruiser. The bottom line ... Toyota did not incorporate salt into their frame consideration. Probably because this is a fraction of their WW market.

Never Ever use spray "Rubberized Undercoating" as a DYI ... it ultimately flakes, trapping moisture underneath that accelerates corrosion.

I have been doing fluid film every year since we got our 19 GX and it quite honestly looks brand new, i just buy like 3-4 spray can bottles on amazon and hose in inside of the frame and outside of the frame as much as I am able. I literally do this by laying under the car with one side of the car up on a curb so I have some more room to move around (we're city folk and I don't have a garage). You can certainly do a better, more comprehensive job if you have a real compressor and sprayer and some wands to get inside the frame but I have found (from owning a lot of toyota's) living in the North East anything is better than nothing. This said, I am super happy with Fluid Film so far and will hose it down every year.
FYI, I also do this on our 4Runner, that I neglected to undercoat for the first 4 years of ownership, and the difference between it and the GX is evident. I have been able to "Rust Neutralize" the surface rust that was showing on the 4Runner, but it would have been much easier to do it from new like we are on the GX, so i applaud you for doing this now and not waiting!

Always good to do regular underbody pressure washing in the Winter months. Best to not do the underbody in an automatic car wash ... more than several posts on this forum where the GX had electrical issues as a result.

The MTM undercarriage has 4 nozzles, so not expecting much pressure distributing through 4 nozzles at max @1800 psi. I'll pass this under when the weather lets out periodically during the winter and planning to do 2 days prior to the rust proofing procedure.
