Looks good. the bubbling shouldn`t cause you any problems, it is sealed.
I have used a brush for all the projects I have done with POR. It is
amazing how the paint will flow and not show brush strokes. You were
hampered by the bad weather, but as long as it is sealed, and preped well
you should have no problems. besides, the gasket will hid all the imperfections.
To make you feel better, Iam in Carson City,NV. and it is cold and snowing.
