Big update on Vader though. the helmet was amazing, but the upper part of the dome had a few thin spots. And the inside of the flare also needed to be sanded.
I smoothed out the flare, and slush cast a few coats of urethane resin to build up the thickness, and keep it smooth. It added some weight, but I would much rather it be more durable.
I also thought that the shoulder armor didn't look thick enough, so I added a pretty good amount of Bondo to the inside.
Then all of it was sanded smooth, and it has a thickness of about 3/8"
Once everything was sanded relatively smooth, I sprayed a good coat of a high build primer. This smoothed everything out even more, and sealed the epoxy very well.

I built this paint bench this past January, and it works great. But I still use a halogen shop light, and a fan to quickly dry paint. This will be ready to handle and sand in about 3 hours.
I also go the face cleaned up and primed. I love they way it looks.
I also did some cleaning up, and found the old fiberglass shins that I cast a few years ago.
These are far from perfect, and are very heavy. But I'm running out of time, so I will do a quick sand, and paint them for the premier. Most people won't be looking at them anyways. I will go back and make a very nice epoxy set.
More painting tomorrow, and the helmet and shoulder armor should be done. Up next will be the chest and belt boxes.
