There is no issue with it inside or outside the FB. It's not meant to be a lube. It's meant to leave behind the solids. Common use is O2 sensors on a car manifold. If you have ever opened the hood of a car (especially a turbo one) after driving it hard it's not uncommon to see the exhaust manifold glow orange. Many cars have the manifold wrapped to do 2 things 1. Keep the heat from damaging underhood components but also to keep heat in the manifold and "light off" the sensors and catalysts even faster. Without antiseez/Never Seez you would never get those sensors out to replace them. If you have ever taken one out you would have noticed there is no "oil" left behind on the threads only the copper or silvery residue. That is the design of the material. So once your grill gets hot whatever was going to "burn off" is long gone and nothing to be concerned about
