Well @Mark Maras, I have to retract my previous claim that water won't work.
I put a little blob of the dried out compound in a small cup and added a little bit of whatever I could find in the area. Naptha, WD-40, carb cleaner, mineral spirits, acetone. None of them did anything at all even with way more than enough mixing. Just did not want to combine at all.
So, since everything oil / petroleum based just ran away, I decided to retry the other (water) camp. And after starting over with a fresh blob, I added a some water and mixed. After a bunch of mixing, it started to loosen up and once it started to loosen, it went quicker. So in the end, water was the answer, but I had to add more than I expected.
It was kinda like adding corn starch wrong. You get lumps and if doesn't look like it's going to work. But if you add more water and mix enough, it eventually smooths out.
Thanks for the help!!
