i had some sufface rust on my 12 gauge .. i hit it with a sisal/black it took everything off .. bluing and all .. i did the whole barrel now i need to either do 2 thing's reblue it or blacken it ....
sorry i went off the topic ....

now for anodize remover ... oven clean will remove it quick most high end stripes work but for the problem i can see that you are talking about you can glass bead it and wet sand up to 1000 grit then hit is with brown or had it chromed .. but the car maker's did the trim in diecast alot of times either way it can be polished but having it rechromed will make it look more stock
