Unlike my first R2-D2, which has a 300mm dome, the blue ring does not come off. With this dome, you need to carefully tape up and paint it.
The dome ring has the spot to be painted already pre-etched into it. The tricky part is carefully putting the painter's tape on the lip/edge of each side. If you go slow and use your fingernail, its not too hard to sufficiently cover up the areas that need to stay unpainted.
Just for good measure, I went around a second time and double-checked. It sure beats trying to remove paint from a tiny crevice.
With that done, I took advantage of the great weather today and used Duplicolor Etching Primer on the dome ring.
And....I also put the etching primer on the pieces I treated with filler primer and sanded smooth the other night....
The pieces will get some light sanding (400 grit) and be ready for the blue formula anytime.
