If only "a few hours" had passed when you noticed the wrinkling/sagging on the baits, you most likely could have simply removed the baits from the wheel, hit them with the heat gun, rebrushed them and removed the excess etex...and then placed them back on the wheel.
Etex takes many hours to solidify under most conditions and you have quite of window during which you can rectify sags and runs...if you pay attention to the baits for the first few hours after you put them on the wheel to spin.
