I did manage to get a chunk of work done on the porch, but since it started clouding up I packed it in. Part of the process involved sealing the sheathing with thinned polyurethane, which takes some time to dry, and I want it to get at least tacky before it rains. And really, I'm still pretty beat.
Discovered that the DVCPRO deck has some wonkiness. I'm going to pull it tonight and do a major headcleaning and see if that fixes it; otherwise I have to bring it in for a costly repair ($85/hr labor plus parts).
