i tried the buffing thing too and it didnt work that well. i ended up masking a bunch of it off, sanding it down and hitting it with some primer so that it doesnt rust anymore (i was having a little surface rust develop).
my wing (slp gen1) is held on by two or thee screws total. i couldnt get the others to line up and i didnt want to modify anything. hasn't flown off yet.
