I have only baked white metal models. For those models, I remember using red oxide rattle can primer, floquil paint, and then baking the whole thing at about 150-200 degrees in a toaster oven for about half an hour. Definitely don't exceed the melting temperature of your solder, and don't bake any plastic parts. I think I chose between 150 and 200 because 150 is not much warmer than it gets inside a parked car here in arizona in the summertime, and I know automobile engines are painted with hi-temp paint, and they aren't designed to run hotter than about 225. You may try googling the net and find temps that other people have used with model paints.
