Starlight Jayhawk Build Part 15 White Undercoat

I went ahead and did a primer and white undercoat before gluing on the fins. There is just too many areas around the tailcone and flare tube I wanted to be sure were smooth and filled.
The fin lines were masked with a thin masking tape strip. Here you can see the masked area after the tape was removed.


After removing the tape, this white undercoat had a masking ridge. This raised paint area would raise the root edge of the fin when trying to glue it down.
I lightly sanded off the ridge with some clean 400 grit sandpaper. Note I said "clean".
TIP: When sanding white paint, be sure you use a new piece of sandpaper. Any paint color left on the sandpaper (from a previous color sanding) will transfer onto the white paint.



At the front of the fin joint you can see where I masked the root edge line a little too long. The tape should have only gone up to the taper along the leading edge of the fin.
