So awhile back I made a impulse purchase. My intentions were good but motivation to carry through was bad. That was 7 months ago.

I bought a product called Corrosion X. There are a few products like it on the market and in my opinion this and ACF50 were the top choices. When the wife placed an Amazon order I tacked it on.

I had to make an application tool to fog it into body cavities like rockers, fenderwells and doors. The three trouble spots.

The applicator is a simple Tee with 1/8" small engine fuel line to the product and a short chunk of 1/4" waterline to the air gun. The magic was the making of a venturi to make the product suck from the bottle. That was a piece of 1/8" brass tube available at any hobby shop or places like Hobby Lobby. Just grind an angle on one end and insert into the Tee with the angle facing away from the air inlet. To cut the tubing shorter just use a utility knife and roll the tube with the blade. About 5 seconds later you will have it cut.

With mine if I supplied to much air it would bubble back in the container. That's ok as it doesn't take much to atomize the product in spite of how thick it is. I had my shop fogged up pretty good by the time I was done. Next time it will be done outside or I'll wear a mask. I used about half of the 16 ounce bottle to do the rockers and rear fenders. The doors I just squirted some in the drain holes and let it run on its own accord.

3M cavity wax #08852 aerosol with 08851 nozzle kit.
The nozzle kit allows spraying 360 degrees inside a box section such as a frame rail or up in a door thru the drain holes. Fast, convenient, OEM recommended.
The 3M stuff never came up in any of my searches. BUT... I really suck at searching the interweb. The ACF 50 sounds like it is pretty much an aviation thing where the Corrosion X has some military specs to it with a broader reach than the ACF 50. That sounded good to me not that necessarily means anything!

Time will tell if I wasted time and money. Can't hurt though!

I like it. I have been wanted to spray some ospho inside of my cab corners. After repairing the passengers side several months ago, I know there are some welds in there that I can reach. Your spray tool just may do the trick. The outside came out grate, but I know there is raw metal under the repair. There are 2 rubber plugs on the back side, but they aren't perfectly lined up with the repair.

My 90 has a large opening at the rear right at the cab corner. I sprayed in that opening. There were also drain holes simular to the doors that I sprayed into. Lots of fog came out the other holes.

I recommend opening up the "outlet" of the Tee to allow as much air as possible to exit. I was really surprised at how much the C X fogged given how thick it is. I may give the rockers another treatment in a week or so after the initial treatment gets a chance to "soak" in.

PS. They make a spray tool if you want to spend the bucks but I had everything I needed laying around.

In my opinion no need for fancy or expensive products. I’ve been shooting motor oil into the panels of my vehicles since the early 80s. When done you need to park the vehicle off the cement and let it drip. unlike a spray product, motor oil is liquid enough to penetrate most seams.
