I  have  been  trying to  stain  some POC  shafts  for  several weeks  now,  with  poor results, I tried sanding  off what  looks  like  a small coating of a  clear  coat  which  I   imagine  the manufacturers put  on  to  weatherize  the  shafts during  storage  and  shipment,  also  tried  using a  stain  prep  to  help  the  wood  absorb  the  stain- still  with poor results,
yet  the web  searches  I get  say POC takes  stain  well, what the  deal  here???
