I'm in the same boat Brent. I've got so much fodder to get rid of I should just start giving it away! The only time I get to make stuff is after the kids go to bed or on weekends. I do try to make at least one big complicated custom a month and a small number of repaints or simple part swaps. I think I'm averaging one a week.
Rolling Thunder was a great toy back in the days. It just shows that if Hasbro wanted to make a cool star wars vehicle they could just modify the GI Joe Rolling Thunder with some new paint apps. Nice modifications you made. Now detail it with some snow and blaster effects.
Believe it or not a Microman body really does paint up well. The hard plastic really makes the paint tought on the joints. It doesn't peel when moved like Hasbro plastic does. The best is to just prime the figure, paint, then cote with dull cote. You should do this with hasbro plastic anyway.
Great use of overkill for these droids. I'm planning on using Overkill to make Klickson from Droid World someday. These droids fit nicely in the star wars continume. I agree that CC would keep his droids in tip top shape. It just shows that someone in the star wars universe washes their equipment once in a while.
