To the best of my knowledge the rubberized coating is to keep noise down when the tires kick up pebbles and road debris. And yes it is from the factory
Why do you want to remove it, and if you were able to, what would you put in it’s place?

From the factory. Why would you want to remove it?

I'd like to get some more of it to cover other areas that weren't covered at the factory.

I wouldn't remove it, just spray the frame underneath with fluid film or whatever you're going to use, should be fine

As rubberized undercoatings wear, they can trap moisture between them and the frame causing rust. I prefer oil based undercoating.

I get the vehicle under coated every year to prepare for the winter. I try to clean as much dirt off of the frame and body as possible prior to this.
I bought the Runner last August and didn’t get the chance to do a thorough cleanup prior to its undercoat application.

The wheel wells are not where you need the product really it's the frame and underbody areas, inside the body panels. I wouldn't worry about washing off dirt unless you have mud caked up into areas. After my annual application at RustCheck I try and find a nice dry construction site road and drive up / down that, stopping a few times to let the dust settle up on the underbody, adds a good layer to the product and makes it more resilient to the 4-5 months I have to drive along roads full of brine and rock salt. I save my underbody wash routine for the Spring.

Canada must have a lot harsher conditions than we get in Oregon. (rain 8 months a year)
I'm just curious, How long do you guys keep your T4r's for? Is all that really worth the extra hassle, cost, etc.
How much longer life are you getting out of all this treatment?
Before we purchased the 4Runner last year we unloaded our 2000 Jeep TJ and 2001 Cherokee, original owners and they both had about 250K on them (kilometres). They fetched 7500 each (Canuck Bucks) because pretty much every spot on their body and chassis was perfect, small surface corrosion only. They were both on original brake, fuel lines and exhaust (daily driven). Even the guy who certified them was shocked that the upper rear ends were in such good condition considering what we get dumped on to our roads in winter.
That brine stuff they started using to pre-treat roads for the coming ice age is brutal. That spray mist creeps into areas and starts corrosion where never seen before, it dries like cornflakes on top of everything. When it dries up nicely it leaves a powder on the road, feels like driving down a desert road sometimes in winter. So yeah = thats what we have to deal with in these particular parts so fluid film type or special low viscosity products are the recommended way to go if you want your vehicle to still look decent in 5-7 years yet alone be able to turn a bolt underneath the thing :mad2:

I bet a heat gun, some heavy long gloves, and a metal scraper would make quick work of that rubberized stuff.

OCD much?
Peeling off factory paint protection to redo it is a bit absurf, imho. Might as well call Toyota and ask them to just send you the truck in parts so you can hand dip them and them assemble yourself.

In my opinion it is totally worth the hassle. My previous vehicle was 9 years old at sale and I had it for about 7 year. No rust whatsoever thanks (at least in part) to my preventative measures. Our salt season runs as long as Dec-May; sometimes shorter, sometimes longer. I also do a lot of Watersports so I’m in a salty coastal environment year round.
Without any data to back it up, I’d say rust is the biggest vehicle killer around here. It’s always possible that my vehicles wouldn’t have rusted without due care, but for me the insurance is worth every penny because once rust starts it’s a rapid downhill decline from there.

OCD lots.
We would all be a little bored if we saw it as absurd to peel off a factory part/application just to reinstall a part/application that better fit our needs. For me, this is a mod just like any other, no different than adding any other after market part in place of a stock one.
