Thanks for the idea, Don.  I had assumed all acrylic artists' products dried fairly fast, certainly with a week or two!  When using gel medium in my actual painting, does it need longer to  set before putting a polyurethane coating (water based is OK, right?) over it?

Dear Don,
  Despite living in a humid climate here in FL as you do there, it has been a surpise to me when some acrylic paintings I had laying on top of each other stuck with some of the paint coming off!  It seems that the acrylic medium wasn't dry even when I thought it was.  How long should I expect it to take for drying do you think?  Would using a hair dryer after a few days help assure that stickiness won't happen?  Setting them out in the sun?  One also stuck to a frame where it touched!  These had been in the a/c studio area for at least 10+ days.  I had no idea from feeling the surface that it wasn't completely dry. 
  I do admit that I tend to use gel or medium in most of the work.  I like the texture, but I was sure they were dry.
  Very annoying.  Suggestions?  Thanks, Brownie
