Use nitromors..i applyed mine onto the frame with a knife because i didn't have a brush,took quite a while but it is well worth the effort,the paint should pretty much instantly come off,i would go over the whole frame twice to make sure you have every part of it done,and when you first polish it,it should go dark grey,then apply a second layer of polish and hey presto ! it starts to turn chrome/shiny/mirrored.The polish i used was 'Autoglym metal polish' (It comes in a really shiny rectangular box) it can be bought from any good car shop.if you add me to msn i can send you some pictures of mine so you know what it will turn out like Hope this helped matey,good luck! zoo baby ! msn : slotcar1990@yahoo.co.uk
