Corrosion Free rustproofing?

I've been doing a bit of reading about the rust proofing chemicals that are available and discovered a lot of reference to this study by the Canadian Armed Forces RMC: http://cradpdf.drdc-rddc.gc.ca/PDFS/unc53/p526285.pdf

TLDR; the report basically says that Corrosion Free out performs Krown and Rust Check formulas.

So I went to the Corrosion Free website and discovered they sell DIY kits -- which is ideal as I want to spray my Harbor Freight trailer, my trailer hitch receiver, and the steel skid plate on my motorcycle, etc...

Instead of getting the DIY kit including the sprayer and a very small bottle of Corrosion Free, I just bought the 1 gallon jug for $60 and free shipping.

Now that I have opened it up though... it appears very thick. Much thicker than paint so now I am wondering if my Campbell-Hausfeld DH4200 will even spray it? The CF DIY kit includes a siphon or pressure sprayer (by the looks of the picture), so I guess it should work.

Does anyone here have experience spraying Corrosion Free? Any tips?
 
you have a spray gun? and their gun is more like a uncoating gun....

you can try it . spray guns are for much smaller particles, and thinner material - this stuff migt not spyay out as nice.
 
Engine warmer in your spray container?

Use a paintbrush to apply?
 
I look into this topic last year when I got a new Mazda. My own conclusion was, DIY is too much hassle, just let them apply it (I went with Krown, mostly because they are close to me).

My other observation after the first application: I don't think I will be doing the treatment every year. It is messy. It's supposed to be a not toxic substance, but I don't think it is particularly healthy. In Toronto, maybe do it once every 2 years. But it all depends how long you plan to keep your car.

Mazda = you'll need it
 
Krown or rust check every year. I'm not exposing myself to the stuff while it's being sprayed/atomized I'll let someone else do it.

Yeah, I'll try the spray gun I have first but if that doesn't work I see that Princess Auto has an undercoating sprayer for only $20.
 
Welp, it worked.

My sprayer is able to spray that goop out, and in no time I had my entire harbor freight trailer sprayed, the skid plate on my bike, and all of the metal parts on the under side of my car. This stuff also goes on clear so I sprayed the inside of the hatch and the hinges -- no doubt I didn't do even 1/3 of the job of the pros as I don't have a sprayer wand to spray inside and I didn't remove any panels to spray behind, but I got the majority of the exposed bits anyway.

I also decided to run an experiment with this stuff. I took a length of steel, scoured it with coarse sandpaper, and cut it in half. I sprayed corrosion free on one half and left the other untreated. I then dipped 1/2 of each of these steel pieces into salt water and will leave them out on a table in the backyard to see how they weather.
