Finished one of the things I knew I had to do, a leak test. The commercial Sealtech system uses a blower inside the TT and they state a .6 inch pressure to uncover pinhole leaks.
Here's what I did. Mounted a conventional forced air blower in a window and sealed the roof vents off, inside, with cardboard ad foam. I forgot to seal the furnace duct and thats probably a good thing since I had 1" of water column according to my DIY manometer.
The result: about 20-30 pinhole leaks, some I knew were there because of my caulking skills and some popped up. The good news is that all are in places whee I can recaulk and the Eternabond tape had the smallest of micro leaks along a tape juction. All of the rest of the roof is 100% sealed.
