I have a gas range (gas stove – indoor) for cooking, and the metal grate that goes over the top has some areas of rust.
If I was to sand down the rusty areas, would it be advisable to paint it with a high-temperature rated paint, such as Rutland 1200 Degree Brush-on Stove Paint or Black Porcelain Repair Enamel?
The main concern I have is not about the effectiveness of the paint product at adhering, but the safety considerations of having a paint in contact with a flame when preparing food in a pot on-top.

Given the direct flame exposure, and that the flames are actually quite a bit hotter than BBQ paint is rated for (1950C for natural gas, 2392C for propane) I'd suggest sticking to clean, coat with vegetable oil (wipe on a thin layer) and bake. This makes a pretty good finish, and does not involve anything that's not going to happen in normal food preparation as far as "what might burn off."
Wikipedia on flame temperatures. These are probably a touch high for "in practice", but given that they are also in Celsius, and the grill paint is rated in Farenheit, I'll stick with "grill paint will burn off."
