If its aluminum, it will corrode into a hard case and stop. It will look terrible.
Its hard to anodize the parts after the fact and thats what the corrosion process really is (accellerated corrosion).
If they don't fis it - clean it up, degrease, and apply a laquer finish to salvage the gun.
Good luck working with browning. Ask them if these missed a silver anodize process if its aluminum.
