How does one go about painting already painted radiators?
Do you sand or strip it, and if so, what do you use to sand or strip? Do you use TSP or a primer? Do you need to use a certain type of heat-resistant paint? If so, which one?

As you know, radiators circulate hot water and the heat from the hot water is what heats your house. If the paint on radiator is on solidly and you don't mind the look of paint over a scraped area, you can go overtop of the old paint. If you want to strip it, use a standard paint stripper. All of this is assuming that the radiators are cold and not hot at the time of stripping and painting. If they are hot, shut them down until they are cold. You should use a silicone or silicone modified alkyd paint that is formulated for heat resistance. Most paints will resist heat for a while but the longer they are exposed to heat, the less resistance they will have.
