I have an aluminum thermostat housing, it has quite a bit of pitting and corrosion on the sealing surfaces and also where the radiator hose should clamp. I am thinking of finding some way to "deck" the sealing surface, but I can't think of a way to repair the pitting on the hose outlet. Is there a way to repair aluminum? If it was steel I would fill and grind, but I don't know much about aluminum. It would be easiest to just replace the part, but Cat wants $700 for it
