I assembled the hull and deck before painting including the dive planes and rudders. I did the conning tower separate. I used spray cans on those pieces. It seemed to be pretty easy way to go. In previous models I would paint all that stuff first but found I then had to do a lot of scraping to remove paint from the glue surfaces. Masking is a little tricky but not to bad.

I wish I had a small drill tool. The flood holes would look alot better that way. I painted mine.
