I asked the same question some time ago. I think Richard Quick advised
that acrylic (perspex/plexiglass) was highly desirable as a coil-form and
it needed no preparation before winding began (provided of course that it
is clean!).

Hope that helps

[ Note that you should NOT clean the acrylic with alcohol or acetone.  
  One subscriber destroyed his form when he cleaned it with alcohol
  (methanol, ethanol, or isopropyl, I'm not sure).  It cracked and just
  broke up. -- Chip ]
