Im sanding edges in bangles with a rotary tool, but this is leaving white marks and scratches. Is there a grit I should be using with this tool, and does the sandpaper NEED to be wet? Ive tried to use polish but doesnt help really. Please help me!

Hi Phyo,
I generally only use a rotary tool to get off big round edges or pieces that would be too tedious to try to work off with sandpaper. A rotary tool is great for taking down rough stuff in a hurry. Once you have gotten the edges off, then I like to use wet/dry sandpaper on a flat surface. Yes, it needs to be wet so that the friction of sanding doesnt melt the dust back into your piece. Start with a 400 to 600 grit paper, then work down to a 1500 or higher grit. Heres a video on the Resin Obsession you tube channel that should help explain what Im talking about: http://www.youtube.com/watch?v=fWii42EtJkM
