Order of assembly? From a bare shell

Thanks for the kind words Fred, much appreciated.
Matt, im just rolling it on. 2 coats so far. I will spray bomb for nooks n crannies missed spots after. Hoping to undercoat before winter but we will see lol.
You got a good shelter more than I had till a few years ago. I think your encouraging us to do a better job.

Looks great. Whatcha using? Spray? Brush? Roller?
