PENETRATING OIL - Make Your Own -- UT-117
This is from the GrassRoots Motorsports board - interesting test.
Rusty bolts? Make your own super rust penetrant!
Suggested by John Brown
So you deal with a lot of rusty nuts? Go down to the hardware store and buy some acetone, a quart of Dexron Mercon and a refillable spray bottle. In the spray bottle mix the ATF and acetone in a 1:1 mixture.
Spray away and get your nuts loose!
