Painting on the sprue

[Foxer]

A picture's worth a thousand words. After removing ALL parts from the sprues, I paint holding parts with these simple, cheap part holders, sometimes aided with toothpicks or pieces of tape ...

Short answer? Yes. And No.

However...let's be honest. Most of us don't build that way every time. I sure don't. Depends on the kit, depends what I'm trying to accomplish with that build, and it depends...frankly...on how much I care about the finish on that given part on that particular model at that particular moment.

Couldn't have put it better myself. It's all about the situation at hand, at that particular moment.
