Picked up my deck boards today so will finish that job this weekend.
Also, my Trane XE80 furnace draft inducer exhaust vent motor starting making some noise last night so I shut her down and have a replacement coming tomorrow. Never did that job but looks straight forward enough.
I sprayed some Kroil on the sheet metal fasteners and will wire brush before trying to back them out.
