I've acquired a basic aluminum downdraft intake. There is a small divot in one of the mating surfaces that I would like to fill. If this were cast iron, I'd use JB Weld ExtremeHeat, but since it's aluminum I'm unsure what to use. Can anyone recommend a product that's both suitable for the purpose and inexpensive (since I'll probably only need it once or twice)? I'm thinking some kind of metallic paste or epoxy.
