BinghamtonEd,
For your application, the wait time you used was probably adequate. I don’t know if 12 hours is over kill or not. I plan to stain towards the end of the shop day, usually. And, it’s often more than 12 hours before I get back to it.
at any rate, it’s always dry, which is the goal for me.
