Powder coating masking

dogsballs thats the point, getting a very abrasive pad that will go through the paint and not just scuff up the paint. will take time but will give a more uniform finish.

Simply attach a high grit paper (600-1200 ?) neatly to your brake pads with double sided and spin spin spin those wheels (not while you are riding) - might take you a couple of hours though.

Keep a bottle of water on hand to keep the sand paper wet (to stop clogging) and to cool down the rim.
