I just tried the "Q-Tip and Acetone" test on a Jim Davis autograph I suspected was a PP, and when I rubbed the signature, some of the ink bled on to the Q-Tip, AND some of the ink (and only from where it was signed) started running through the back. Seems to be a pre-signed authentic.

Anyone have any experience in this kind of testing? Different opinions?

I heard ink will come off with dry erase markers. Maybe you try that too?
