2021 rusting?

I’ve had Corrosion Free applied twice so far on my 2020 and no rust issues yet. It’s a bit expensive to have it done at a local shop but I think its worth it. I also like that it doesn’t drip.

 

Neither does cosmoline if you sprayed on a 90 degree plus day. It seeps into joints, and sets up in 15 minutes...dries in an hr. Not a spec. of rust on my 2020 and i only applied it once.

 

Tacoma's have a plastic no rust bed, Stainless steel no rust exhaust, plastic no rust fuel tank, galvanized no rust body panels, etc. Why not hot dip or plate frame? Why! Why! WHY!

 

I use cosmoline in the easy to reach areas (probably 80-90%) of the frame areas, and FF in areas harder to reach since it creeps better and gets in places you can't really see

 

It’s a tradition.

 

As far as their stainless exhaust system, it does rust, especially at the welded joints. Their good for 10 years, at least in our new england climate.

 

Mine is still solid after 11 yrs. in eastern Canada.

 

This is going to be controversial. Someone please prove me wrong, but paint is a much better solution than fluid film, cosmoline, etc. for corrosion resistance. It’s more durable, and doesn’t attract crud. Use lubricants for moving parts that cannot be painted due to frictional wear.

The catch is that there are nooks and crannies that are hard to inspect and hard to paint. This is where extra corrosion prevention can be necessary. The good thing is that (I think) Toyota has taken care of this for us.

I sand off the rust and repaint my rock sliders and hitch receiver each year before winter, but haven’t bothered to do the same to the frame. I have thought about it though. It would be a much bigger job.

 

The issue with paint, as your only protection, is your frame gets pitted by debris coming off your tires. Once scratched, it’s compromised and corrosion starts. “Soft” top coats like fluid film and cosmoline don’t get nicked and scratched, but eventually need reapplication.

You have both unless you live in a sunny state far from the ocean.

 

yep, depending on your level of OCD, to properly treat a frame that has been nicked and started to rust, you need to sand it, spray with a rust protectant like rustoleum, POR-15, paint over it, then treat it again with a protectant. Thats really the only way to stop rust, anything else is just masking it and delaying the inevitable

 

I’m talking about reapplying paint on a regular basis if it gets damaged.

Also, my personal experience is that you don’t actually need anything on modern automobiles. You rarely see rusted out jalopies on Minnesota roads these days like in the 1980’s. I owned a 2001 Subaru for 15 years, never rust proofed it, rarely washed it, parked it in a warm garage, and the only serous rust it developed was in the roof rack and under the windshield molding. I blame the windshield molding rust on a botched windshield replacement job

 

Our trucks have bigger tires and more frame surface area exposed to road debris, kick more rocks, frame gets nicked, chipped, trucks rust much more easily than cars

 

I’m skeptical. Do you have any evidence of this?

 

I can show you my frame vs one of a jeep or tacoma thats untreated and you'll believe...lol

 

I got my 2021 last January 6th. I immediately sprayed anything and everything with fluid film when i got home. After every so many washes i touch up any place that looks like it needs it. So far its doing great. Only reason why im so hardcore about touch ups is because where i live, they salt the living shit out of the roads. Salt, brine, and some other crap i never heard of. This summer i may look into something professionally done. But the fluid film is easy and works. 3 cans or so should be good for the first application.

 

This is what I consider a serious rust problem.

My 1974 and 1981 Datsun pickups looked comparable to this way back in 1987. RIP, rust bucket pickups.

 

Idk, about that. When a buddy had jeeps he'd restore and drive year round here, he only believed in paint using this chassis black stuff. He'd be repainting the chassis every couple years to keep the rust at bay. He's now a huge cosmoline believer.

 

^This is the way

 

There is no down side to adding the protection, the cost of a good Cosmoline job is pretty small both in money and effort and will keep you truck in good shape for a long time.

 

Most current lower vehicle bodies are plated or galvanized before painting and this protects them in rust belt areas. Undercarriage items such as chassis, suspension components, drive components and such are just painted and subject to corrosion. While annual painting them may help it is almost impossible to clean up and paint inside box sections and tops of frame rails without disassembling. Undercoating can be sprayed and will creep anywhere water can get and will protect exposed metal from corrosion. Control arms on my 09 Forester were recalled due to corrosion problems causing failures. Mine were fine due to undercoating annually but were replaced anyway. Recently had my 11 Tacoma in for chassis inspection but was ok. Had it not been rust proofed annually, it surly would have required replacement. Coastal eastern Canada is probably the worst place on the planet for vehicle corrosion. Mild winters, lots of road salt combined with moist salt air blowing off the ocean. Hell, Even the new Tacoma chassis' sitting outside the dealership awaiting recall replacement were rusty.
