RE: Gregers first tip...you can also use a hole punch to knock out small discs from those sticky pads and use them on the end of a piece of dowel, sprue, etc to get into small areas. They're also available in very fine grits in small discs, maybe an inch or so in dia.
I use plastic straws for mixing/transferring paints. Cut to a length that suits you; stick into a jar of paint, thinner, mixed paint; put a finger over the top, lift and transfer to another bottle, airbrush cup, whatever. Works great for stirring too...
I've started using Castrol Super Clean for a lot of things. I keep a RubberMaid container on the counter that holds about 3/4 gallon of the stuff with a couple inches to spare. If a paint job goes horribly wrong, it goes straight to the tub. Fresh paint strips very quickly. When I'm done spraying, the paint bottles, feed tubes, air caps, needles, etc takes a dunk and clean up easily. I keep a little flour sifter with the handle cut off and bottom flattened in a corner of the tub so the small parts don't get lost.
I realize at times you may need a stronger paint remover and you shouldn't use CSC on resin but, for 99.9% of my paint removal needs it works just great. And isn't nearly as messy as brake fluid or Easy Off. Filter out the sediment and use it for a drain cleaner when you need a fresh batch. Bio-degradeable. Simple Green, Greased Lightning, Westley's Bleche White should all do the same. Just wear rubber gloves...(and test first of course)
