Hey peeps, I have a XP 2000+ and my bro has a 1600+ that we would like to try and unlock. I am running an Iwill XP333-R. I have read about the different ways to do it (use and eraser or crayon to fill up the valleys, etc.) then apply conducitve paint. I would like to have a very professional looking result that looks like it took more that 5 minutes to complete. Any help would be greatly appreciated. Thanks
