Just curious...is there any way to remove paint from canopy pieces, etc, without scuffing the plastic up and making it look terrible? Say I'm carefully painting the frame lines on a cockpit canopy (which I do by hand, with a brush), and I slip a bit, leaving a little bulge in the line. It's difficult to wipe it off without smearing it around worse, and if you let it dry, you can't scrape it off without ruining the glossy finish.
Is there any trick to removing that tiny extra bit of paint and leaving a nice straight line? Some powerful solvent that can be very carefully applied to just that tiny area maybe? I'm not getting my hopes up, but I figured I'd ask anyway, since I hate having one little slip mess up a whole canopy, especially when I just spent an hour painting the rest of it all carefully.(Of course, I could just learn how to tape it off...but I've had poor luck with that the couple times I tried it...I'm no expert modeler!)
As a bonus question of sorts, I'm just curious...what kind of plastics resist being glued together? This isn't a model kit I'm talking about (that would be kind of pointless!). It's just that my nephew (of sorts) has a (about 1:48) toy Spitfire Mk II that he got like a year ago...he's like 11, and is getting all into the whole WWII aviation thing, which I encourage. Anyway, he dropped it, and the tailwheel and one of the props broke off. I tried two kinds of superglue and even regular old modeling cement...it just refuses to bond well at all. I even sanded it back to plastic each time before I glued it, so it can't be that. Is this characteristic of a certain type of plastic they use it toys? It's quite a bit harder and brittle than the stuff they make most model kits out of, but I just can't get why it won't bond. I finally got them to stick back on, but it's very fragile now...bump it wrong and they'll come off again. And 11-year-old boys aren't so great about not bumping things! =)
