Penetrating oil what`s your fav.?

Been using an old can of Liquid Wrench the last few years. I would have bought a can of PBB because it is used and highly regarded by so many people who turn their own wrenches. Guess I'll stick with the LW! The homebrew is very interesting!

Thanks for posting the "scientific" results 440rev!

Does it matter what type of ATF? Dexron or type F?

Here is a old trick I found on the web: I have used the wax trick since I was 15 or so. A old German mechanic taught me the trick and i have used it now for 51 years.
Heat the fastener hot enough to really melt wax. Do not heat it hot enough to change color. If you heat it to hot, the wax will just burn off. You want the wax to be fluid yet not burn.
