Looking for some advice.  The components of my cabinet are cut out of MDO and I am looking for the best method to paint it.  I see that many use foam rollers for this job.  What is the best technique for getting a smooth coat with as little texture as possible?  Should I be thinning the paint?  What type of paint and what type of primer should be used?  Latex or oil?  Gloss or Semi Gloss?  I googled painting methods for MDO and the replies were from exterior sign makers that used some $pecialty paint.  I have no problem purchasing good paint but it should be available off the shelf at Big orange or Sherwin Williams, etc.  I do have an HVLP spray kit but everytime I have painted with it I have gotten the orange peel results even when using Flotrol to thin.  Anyone have a tried and true method?  Thanks in advance.
