I prefer "paint first then assemble" method because I am scared to fit the different color in the right spot afterwards. My hands don´t shake too much but I am getting nervous anyway. And yes, I have to scrape the color off the spots where a glue is supposed to go. Some guys apply a piece of adhesive tape to the joint areas prior painting. After the color has dried they strip the tape off and they have clean spot for applying the glue. I have never done that but I should try some day.
By the way, great build, JT. I like that.
Your initials and mine are sort of the same. So, there goes a greeting from JT to JT.
