| Years ago someone gave me a free crawler tractor and the engine was froze. One of my buddies brought some article from a car magazine that tested different stuff. We tried the 50-50 mix of atf and acetone for probably a month that the article said was best and nothing.
After a month someone else said try some soda and nothing.
I finally tried some aero kroil and the next day I grabbed the fan and the piston moved about 1/4" little effort. After working it back and forth for about a minute the engine was turning over freely.
Yea it's the most expensive aerosol rust breaker in my collection but so is my time | |

Aero Kroil Any Good?
