Rustproof or not??

I am using a cheap gun (from princess auto which is the Cnd harbour freight)that can be attatched to my compressor.

 

i have a question that is puzzling me, maybe somebody knows?

in the past 25 years has the special 'secret formula' Toyota frame paint & coating ever changed or is it still of the same composition?

in simple terms, is the frame paint & coating they used on my truck in 1997 the same quality as they put on the new Tacomas now

 

Short answer is it is either the coating or frame. However, this does happen to other brands of vehicles, but the manufacture doesn't warranty it like toyota.

 

I suspect that coating formulas and frame metal compositions fluctuate over the years like most things on a vehicle... if the paints have gotten better on the panels in the last 25 years then surely the frame coatings have changed too. That said, factory frame coating will only get you so far once a rock chips it or a spot weld starts to rust. Once that happens, without a corrosion inhibitor coating like Fluid Film, etc etc then its all down to the metal composition of the frame itself... which at least in the 2nd gens was not up to par. I think I have seen some people with 2016 and 2017 3rd gens have even gotten letters from toyota about frame rust issues and extended service coverage for them...

 

Krown is great for inside frame/body cavities and it creeps like crazy but I find it tends to wash off easily in the winters even without going through car washes or power washing it directly....
IMO, FF is a shit-job to apply but sticks to undercarriages a lot better than Krown and creeps just as much. Worth the money and time once per year....

 

. I am guessing that my little pancake compressor would not do the trick or maybe it would?

 

my compressor is only good for 4-5CFM. The gun works at 50-70psi off the top of my head. Yours would be running/pushing it a lot. Mine was working hard but it sprayed fluid film in the cold for me...

 

The fluid film website recommends 1500 to 3500 PSI with a sprayer that is for paints and such. I don't know much about compressors and such but they called it airless sprayer or something like that. When in doubt, read the manufacturer recommendations.

 

Per the FF site https://www.fluid-film.com/frequently-asked-questions/

"The most efficient way to apply FLUID FILM in its bulk form is with the use of standard airless paint spraying equipment. Airless paint sprayers operate under high pressure, usually between 1500 – 3500 PSI, which atomize paint into tiny droplets, propelling them towards the desired equipment. We recommend a minimum of around 2000 PSI. Applied at a film thickness of 3 – 4 mil, this will cover approximately 250 sq. ft. per gallon. We also recommend a spray tip of between 515 -517 for best atomization."

 

meh, I did it last year with the aerosol cans and it seems the same as with my compressor. Airless sprayers are more for industrial applications but yes that would be the best method, or some kind of screw/rotary compressor that can pump out the CFM's. Mine was slow, but it worked.

 

This is why I have this statement Just Rustproof it yearly! in my Signature!

 

wow 3500 psi sounds professional grade and quite dangerous!
probably rip the skin right off your body with that pressure

 

It's certainly powerful. I had a summer job power washing once and they gave me a 5000psi power washer. It was a beast.

 

I like Eastwood for permanent rust prevention as opposed to annual re-coats.

 

Wow that is some high pressure....I think spray cans it is.... thanks for all the replies though.

 

I just got under today since it was pretty warm and gave the undercoating a nice coat. Took about 3 cans to finish the job. Noticed a couple of spots starting to rust small maybe 2 to 4 mm in size behind the front tires my guess is its from rock chips hitting the frame and rusting... I didn't have time to file it down and repaint with rustoleum so that'll be a job for me in the spring

 

Three cans is what I have coming.... nice. Sorry about the rust but it sounds very manageable.

 

I may be wrong, but I don't believe there is a permanent rust prevention solution out there that matches getting it done annually. Especially where salt is used.

 

Ahhh part of the fun living in the Midwest Salt belt territory. Better to catch it early. I firmly believe half the maintenance of FF annually is noticing rust spots like this and treating it early. Those who don't treat never crawl under to look at 90% of their frame to notice anything

 

How do you apply the coat under the car? Just spray it all over? Can it be applied to areas with paint? Is it safe in the wheels area with you have the breaks/disks/drums and all the connecting suspension parts? How long does it takes to dry? Thank you
