Painting the Dome

I'm reaching the next pause in the frame design, so I'm going to spend a little more time on the dome, specifically the paint job.  So far it looks really good, for a first coat.  I'm planning on spending some time sanding it lightly, putting a 2nd coat on, then sealing it.

Because R4 is inversed colors from R2 (the main dome is red, where the pie panels are silver/platinum), what I'm contemplating doing is getting a metal tape/sheeting that I can cut the panels out of to make them metallic, instead of just using paint.  This will give them a raised look (like they are moving parts), and make them easier to install.
