Turning over engines in storage

Allright it looks like that wd40 is getting wiped out of there. Thanks for the input!!

I have heard of and currently use seafoam in my boat. I didn't know they made a spray either.

I have never heard of using diesel, but I have heard of people using ATF.

What about you engine builders? Don't you have an engine or two under the table? What do you do when you have to store it for a year?
