Dear Scott, 
       I use Pro-Par in my processor and am absolutely satisfied.  Have used 
it for years and will never use xylene again.  It is a great product.  If 
doesn't break down as fast as xylene and you don't have to have it hauled off 
therefore, saving money.
Also there isn't any real odor.
