just use more nitromos on top of that cus u wanna make sure all the paint is off then wash it down it warm soapy water,then get some fine grade sandpaper on it for the little bits that wont come off,but make sure u sand the whole frame down good,then wash it again it should be better looking then, then polish the whole frame,just make sure u rub hard, there will be loads of grey crap that comes off but thats normal
