The Staples paper is OK, but not great - It takes a LOT of work to get all the paper off. One that works much better is HP Presentation paper Q2546A -
http://www.staples.com/office/supplies/StaplesProductDisplay?storeId=10001&jspStoreDir=Staples&productId=156882&cmSearchKeyword=q2546a&fromUrl=home&cmArea=SEARCH&catalogId=10051&langId=-1This requires less pressure and heat than the Glossy Photo paper - I assume this is because of the lower thermal mass? - and comes off very cleanly.
A neat trick to help remove the paper: instead of soaking in water, soak the PCB+paper in ordinary white vinegar. The longer you leave it, the easier it is to remove, but about 10 minutes in room-temperature vinegar works great. Then a quick wipe with your thumb or a paper towel dipped in the vinegar and all the glue/coating comes right off.
