3400 rpm on a loose cotton buff
sounds reasonable to me. Quite safe for lexan and plastics.
Kevin, most on this forum have no clue as to the tools that you are using.

talking about foam pads or wool pads here. But, in the interest of least aggressive first, then I must concur with rider9195, if
using any variable speed rotary that is not
a Two- Speed like yours.
