A couple of review point on Bandai's C-3PO.
The gold finish on the parts is very thin. If you're using any glue (mostly unnecessary), take care not to get any on the finish.
The sprue attachment is pretty clever if you know what you're looking for. The sprue actually attaches to the back edge of the part - not the side, as is normally. Turn the sprue over so the back of the part is facing up. Place your snips flat on the edge of the part (the edge you would normally glue) and snip the sprue. Clean sprue join with a sanding stick or knife. This should leave the plated part that shows, unmarked.
The decals are a little thick and I found they don't conform well with decal softener (MicroSol or the more agressive Walthers Solvaset). Several applications of softener may be needed or you can paint the more dimensional areas.
Don't be afraid or embarrassed to use the stickers. They have non-bleed printing and clean (not carrier film) edges. However, they do not work on those dimensional areas mentioned above.
A note about the Bandai Stormtrooper.
This is an almost perfect kit. It goes together well. It's beautifully articulated for posing. It comes with a selection of nicely sculpted sidearms. The gloss white armor and semi flat black parts really need no painting. When assembled it looks like a Stormtrooper. It you think it looks toyish, it can be weathered. The only trouble is that you don't need a lot of skill to build a great model!
