Some of you might find this a dumb question, but nearly all my miniatures painting experience is with the unpainted variety of miniatures. Painting pre-painted miniatures seemed weird, like shouldn't I strip the miniature of paint before even attempting to repaint it? Also if I didn't, wouldn't another coat of paint potentially ruin any detail? Clearly my fears are unfounded, as there are some crazy Armada and X-Wing repaints, but I still have questions (also this thread can't be a terrible idea, since this forum seems pretty active, and I can't be the only one wondering how this goes).
So far I have a core set, a CR90 I bought on a whim since it was at a deep discount, and a Rebel fighter pack as a Christmas present from a friend impulse bought for no good reason (he doesn't even have a core set, nor does he plan on it...). The only real issue with the fighters is I can't make the detail brush get to the model fast enough before the tip dries out.
The CR90 poses a different issue. Should I prime the entire thing and just start fresh? I mean, let's say I want to paint different colored stripes, how would I paint over the red that's already on the ship? I want to do more than just repaint the red parts. Doing a complete repaint poses different issues, though, like the exhaust glow, and that residue on the engines, I'm not sure how to do that myself.
I also have an Assault Frigate on the way. This seems like a really popular model to repaint, and I feel the same way (no canonical appearance means little to no qualms about repainting my only one). Do people just spray the entire thing with primer before getting started? How about the chipped paint effect on a miniature so small? Also, how do you do the thing where you paint only a single panel? That last one seems obvious, but then you have to deal with wide crevices between panels, highlights, deciding how offset you want the panel color to be....
It's been a while, but I have painted a good deal of character miniatures. However, the last time I painted a vehicle was a REALLY long time ago, so I kinda need help in this department :/
