We picked an extremely hot and humid weekend to tackle two long-awaited jobs. One was the re-sealing of the cabin skylight. Permatex flowable windshield sealant topped with 3M 4000uv may have done the trick there...so far, so good! But the real remarkable job was the install of the solar panels, a.k.a. "Sky Lab". I'm really proud of the Captain--totally designed the install of the entire system. While it's not hooked up yet, the panels are in place and it looks good! Bring on 450 watts!
