i think my buddy has one similar. he uses is on his camp stove out in the wilderness. very rough. hot dog and steaks.

i did a quick search on Amazon, and there is a a guy that did exactly that. he sanded it down. his pics look glossy. DO IT!!

i imagine a flat surface like that; the superpower would be pancakes. no way "Sandpaper" texture will get you there.

google, sanding cast iron on youtube and you will see tons of great ones. they use a drill and one of those paint remover disc things. full half mask respirators!! the dust will JACK you up.
