I glued up a test yesterday. This morning I removed it from the jig barehanded.
My normal glue up in a jig like this is to let it set in the jig for about an hour, then set it aside to keep drying.
Usually that's because I need the jig for more glue ups, but also to make sure it comes out of the jig.
It passed that test.

As far as chemicals, Johnson's didn't have ingredients listed on the can.
The only ingredient I understand on the Turtlewax can is the first one listed,water. After that chemical names that I can't relate to.  

I think it will do for this intended purpose. I also have paraffin wax blocks, but they are difficult to apply in this situation, but do perform well. Maybe if I heat it I can brush it on.
