So here is the R5-D4 dome....after sanding off the bad parts and attempting to repaint the whitee without ruining the red pinstripes and the reflective stuff around the neck...

It turned out ok..worst part os on the back. I looked at some screen grabs from Star Wars and it's pretty beat up so I think I'll be ok once I weather it.

The neck piece that goes over the reflective stuff is 1/2 done. I had to file a bevel on each section so that took a while, but here it is just sitting there for now.
My dome greeblies (antenna, hydraulics, eyes) arrived yesterday...woohoo!!
