Refinishing Success at Last!

[Wilsons]

What is PSL?  Where do you get it?  and I think an academic question for
this list is one regarding spray method mentioned below vs brand of
waterbase topcoat.  Webb Phillips recommends HVLP because of the warming
benefit.  It is suggested here that the warm air in HVLP may be a hindrance
to good finish.  Comments?
