Bob and Ken:

We use temporary soldermask all the time. It's great for masking off any
area of a circuit board that you don't want soldered. We use Kester TC-564-1
water soluble mask. We somewhat routinely bake for one to two hours at 90 -
95C. The baking that we do is tied to using HF-1189A water soluble flux. The
boards are cleaned in a Trieber in line cleaner.

 I can't say that I've left masking on for 12 hours at 125C
