Paint job on BD-1

while i am observing the work my son does on his d-o project, i take care of my very own project, bd-1.

unfortunately, the filament lines of the 3d print job are a little bit "raw". i wanted to eliminate the problem by painting a filler/primer to the surface of the parts and applied additional bondo to bigger gaps.
but nevertheless i had more gaps in the end than i wanted o have... 😖

and through these gaps the paint from the rattlecan "soaks" itself into areas beside the paint area. not good!

pic will follow

so i decided to repaint these areas with a small brush. i hope this will work. i hate applying and sanding bondo for hours...
