when u cut / grind one down, what is the best anti corrosive paint I can use to cover the exposed metal? preferably something I can buy in homedepot or, maybe, online ...

I just used one of those Birchwood Casey flat black touch-up pens. Just cut the ears off - not the whole lug.

I used BBQ grill paint sprayed it into a cup and used a brush to paint it on. This was after whoever ground mine down didn't seal it at all so I had to clean up some rust but yeah clean well and paint on

I used birchwood Casey aluminum black worked fine. Just make sure surface is clean first.
