Chuck,
This is a bit outside the forum definition, but it is possible to burnish-in the outlines of flush rivets for stunt models. Same for panel lines... Either alternate layer masking, leaving a hairline of thickness as panel edge definition, or scribing into the many layers of clear dope (for a dope finish) to show a hint of the edges, works. At major meets, CLPA models are scrutineered closer than Scale models at most meets, major or minor, and they don't have the benefit of the 15' rule.
I think, that done well, such techniques could benefit suitable scale models. Almost subliminal, but with effect on judging for representation of the type ansd specific example presented...?
I've only done this once or twice on stunters, which had many other flaws for appearance judging, yet I feel it has potential for both CLPA Appearance judging, and the most popular Scale events.
