Evapo-rust

Has anyone this in a running "A" motor? I would like to try It out, but I don't want to be the lab rat and find out for some reason it causes an Ill affect on A motors.
 
I did the same thing as Mrtexas is doing last year with great results.I also used it on a rusty B carb that I am running on my A now. Also used it in the radiator.
This spring I used it to loosen a jet ski motor that had water setting in it for a couple years & bearings, crank etc were all froze up. It ate enough rust away so I could get it apart.
 
Be very careful when using on painted surfaces. I bought it at a car show,where the demonstrator was cleaning rusty licence plates. Great, I had just bought a set of 1932 Michigan plates in pretty good condition,and wanted to stop the rust from doing any more damage. When I removed them from the solution,the paint was slideing off. I was sick,had to restore the plates,instead of keeping them original.
 
We just did the lab test with engine in car!
First did the vinegar flush, left it in for a few days. Drained and flushed, then sloshed it out with lacquer thinner and let dry.
With the rear end jacked up to get the motor level we pored the whole gallon in the block with the head on. The head had been acid cleaned so was not worried about getting it clean. We had made a block off plate with a drain hose attached for the water inlet. Plugged the water outlet after poring it in and let it sit for a couple of weeks while working on other parts of the car. When I drained it, it might as well been molasses as black as it was! Flushed it with clean water and all I got was a little grit that was in the jackets.
Hind site, wish I had left the head off to see how it did.

Grease kills Evoporust, so any part going into it need to be grease free.
 
I soaked the end of the windshield frame in evaporust for 3 days. with a little heat and a few taps those little screws came out after 80 some odd years. GREAT STUFF!
 
This is interesting. Does white vinegar dissolve the rust, as apparently Evapo-Rust does, or merely work it loose and create flakes to clog the radiator? I just ran vinegar through my coupe, and the water is now running clear, but I have an overheating problem.
 
I bought a hole-free but very rusty 30-31 gas tank from Berts. I built a "tub" out of 1 x 12's a little larger than the tank. I braced the corners of the "tub" and laid a sheet of 8 mil plastic in it. I put the tank inside the tub and dumped 5 gallons of evapo-rust into the "tub." After 3 days or so I turned the tank over in the evapo-rust solution making sure all seams at one time or the other were under the level of the evapo-rust. At the end of the week I had a rust-free tank on the outside. I drained the solution using a huge funnel back into the 5 gallon container. I dismanted the "tub." I then set the tank atop the work bench and poured the used 5 gallons of evapo-rust into the tank. I observed this static test for several days and saw no leaks on the newspaper under the tank. I then braced the tank on one end for a day or two, then on the other end, then upside down (all gas tank openings were plugged). I then drained the tank's evapo- rust back into its original container. I rinsed the entire tank with a gallon of gas, drained the gas and disposed of it. I then put about a pint of MMO into the tank to retard any re-rusting and brought the tank to the painter. I have just reinstalled the tank into the car after draining out the MMO and am anticipating no problems.

It does a good job of disolving rust, but takes weeks to do it. I ran it for 3 days, then a new batch for 30 days late last summer, but now I think I will run another batch for 30 days. This is because my filter has disappeared and I found more rust flakes in the top of my radiator.

I'm going to try blowing compressed air into the rear of the block and my shop vac connected in place of the water pump to see if I can get some more rust flakes out. I've also been thinking of using a large tub of water and a sump pump discharge into the block inlet to see if that rush of water will bring out more rust flakes.

Now I'm wishing I would have removed the head and blown out the block when I had it upside down on the engine stand. Never trust an unknown used engine. For all I know the block could have been filled with mouse nest and crap.:mad:
 
I See A Lot Of Companies Sell Evapo-rust, I Called Evapo-rust And They Told Me That They Don't Use BLUE 5 Gal. Buckets That They Use White Buckets.
My Question Is The Evapo-rust In The Blue Bucket Is The Same Stuff
Here Is The Blue Bucket
Thanks For Any Info

Hey Joe,
Hm, you may have answered your own question , by your investigation/questions and answers directly to evaporust ! This stuff ain't CHEAP,eh ! This presents an opportunity ..maybe.. for some to make a buck. Further investigation is needed. Try a small amount on a small rusty part and see what. I have used this product enough to know what/how it works. So, I would have an idea if this is repackaged real mc coy stuff or snake oil. Let us know. Curious, why did you buy it this way and how found ? If it is real product, and less expensive, we would appreciate knowing, thanks.
BTW..some are saying, well..left it in for few days. NOPE, no where near enough time if bad rust, like in a block. And, best to 'ROD' out block first to get all the chunks possible. Then, IMO, works quicker/better. Great results in my opinion and useage !

got any before and after pics. I also would like to know if it would work well in a gas tank. did the electrolicis on my tank with a 55 gallon drum it took the paint and light rust off the out side I left it in for a week I will try it again next week to see if any more comes off.

No before, but here are a bunch of rusty tools I got off ebay after an over night soak:

I like it too; us it a lot.
The only exception I take to the accolades it that I have found it does soften some paint.
But not a negative with me on that issue

The rust is not loosened. It is dissolved. The solution turns black and the rust disappears. I don't see why it wouldn't work on a gas tank. It would leave you with clean steel and wouldn't affect any coatings.

This sounds like something that could be done "on the car." Didn't someone do something like this by "circulating" the fluid and filtering out any rust particles that came loose?

I think he did some "rocking the car" to try to speed the process.

Well Hardtimes Your Going To Have To Stay Curious, Because I Did Not Buy It Yet, I Just Wanted To Know If Anyone Used The BLUE BUCKET Evapo-Rust
So I Would Know If I Should Get It Or Not,
