Hi all,

I was watching some video from The Fast Lane Truck Youtube channel and they mentioned Tacoma has certain model years prone to rust and there was a major recall to replace many frames. Then I watched one of Scotty Kilmer's vids and he mentioned his Toyota Celica/Corolla doesn't have any rust because Toyota made those cars with the right materials to prevent rust. Are any models years of 100 series more/less prone to rust/corrosion? And how does Hundy compare to other Toyota models and other makes of offroad-worthy SUVs in terms of rust prevention?
Thanks!

In my observation, all body-on-frame vehicles (regardless of manufacturer) seem more rust-prone than unibody vehicles produced in the last 15 or 20 years. Look at any domestic 1/2 ton pickup or pickup-based SUV... It seems like anything I see that is 10 to 15 years or older has rotting rocker panels, lower rear quarters, and hem flanges (i.e. Silverados, F150s, Suburbans, etc.). I'm not sure if it is a characteristic of the design, manufacturing, etc.

It is also my observation that the newer the Toyota, the better in terms of rustproofing/corrosion resistance. I guess this is part of their Kaizen manufacturing philosophy, but it seems like they actively improve this aspect of their vehicles from year to year.

Started Fluid film on my 2015 LX, just coated it this weekend. The truck looks brand new u nderneath. I am i n PA. Fluid film has also helped to slow down the rust on my 2000 lx470.
Great results with this product.

Just moved back to Pa. Had a welder exhaust shop install a new muffler, the original finally cracked after 17 years. He was flabbergasted when he looked underneath-your rig is not from around here. I responded would you believe it spent 4 years in snowbelt of Ohio-fluid film works in preventing slowing rust from salt.
