Good afternoon.  My name is Ray.  I currently live in north central Iowa.  I have been an amateur woodworker for about 35 years.

                                                                                                                                              I am picking up an old project.  It is oak, stained and partially finished, I think with polyurathane.  I don’tremember for sure about the poly.  I didn’t like the color so I re-stained over what was there.  When I put a finish coat of acrylic I got white splotches.  Thinner, alcohol and lacquer thinner did not change them.

Any ideas on how to prevent them and correct them is what I seek.
