I think you made the right choice, and it’s good to have the dealer stand behind their work.

100% rust free option #1 move the flip out of the mid west.
99.9% option #2 park it over winter and buy a beater with a heater.
***% option #3 (best option) keep it clean after each storm and eventually trade it to some shmuck living in the south who don’t know any better.

You've convinced me

How much do you need for one treatment of the 4R? I saw the 11.75 oz cans from Lowes, AutoZones, etc. Do you use these cans or the larger gallon cans?

Thanks again for your insight!

Youre welcome! I use the cans for touch ups, but the product is a bit thinner this way. For your first and yearly applications go to a professional Fluid Film applicator shop. Shouldn't cost more than $100 first application and much less for yearly touchups, which is well worth it. The product they use is much thicker and they can saturate the entire vehicle inside and out. Just do a search in your area or call Fluid Film directly. Never had a problem with it affecting plastics or rubber so just apply and enjoy a rust free 4Runner.

DO NOT use a rubber based product !!...I use a product called POR 15 and it's basically a paint...I did my 2016 this past summer...EXCELLENT product !!...took basically the whole day between all 3 product applications...you buy the cleaner, the metal prep, and the paint. A ***** if you get that stuff on you and it dries...NOTHING will remove it so you just wait a few weeks until it sluffs off your skin

You don’t need paint or anything fancy. I’ve used fluid film via spray cans every fall. I spray inside the whole frame using the frame holes and outside the frame. I use a total of 6 cans and I don’t have any rust. It doesn’t get washed off like some people said and it’s non-toxic. Please don’t use anything toxic as we only have one planet.

Paint does NOTHING. Anyone who says it works on their new 4Runner doesn't have a clue what they are saying. Fluid Film once a year and it will last forever.

i think I can manage 6 cans. I also have the air compressor etc so I might go that way for the initial treatment. Do you remove the skid plates when you spray?

troopa4life · 01-29-2019, 04:04 PM

Good idea, yes, remove skid plates and rear spare tire and go to town.

If you already have rust and want to stop it, POR15 is the best.

If you don’t have rust and want to prevent it, use Fluid Film.

After reading this whole thread and doing plenty of online research this seems to be the best advice. I bought mine used here in the North East and the rust isn't terrible, yet! Plan on going to town with POR15 when the weather warms but wish the PO had used fluid film.
