Semroc Little Joe II Part 20 Paint Plan

I couldn't quite understand the Semroc painting instructions. I went over to JimZs site for the
Estes Little Joe painting information:

Scroll down to page 4.

I plan to paint the pieces separately (from the top down)- White escape tower motor unit, black tower skirt, white tower and silver capsule.

All gluing surfaces will be masked for better adhesion.

Sometimes when painting something complicated, you should plan ahead.

These assemblies would be nearly impossible to mask once glued together.
