Checked on my Proseal, after a week away. The first application batch (on the large cover plates) is setting up nicely. The second application (on the sender plates) is still tacky, but perhaps less so than the last time I checked. I added a second lamp and moved both lamps slightly closer. The temperature at the sender plates is now at least 80 degrees. I'll leave them like this for another week and see how things are progressing.
