After lightly sanding the primer, I gave the dome the first coat of Rustoleum Chrome Shiny Metallic paint. I am very impressed with the results. I am going to lightly sand it tomorrow and then give it another light coating.
I have noticed some stippling on some of the resin parts where maybe there was still some releasing agent on them, despite a thorough washing and cleaning with alcohol. I will sand those spots and touch them up again.
