Norman, Nice doors. Does the building have a rain gutter above the doors? I can't tell for sure from the picture. What was your method for keeping water out of the bottom panel?
Geoff, There is a soffit with a gutter over the doors. We pre-finished the panels and the rabbit that they go into. the panels are then beded into a little silicone. The doors were then finished with 4 coats of spar varnish.
