ditto to the above.
SERIOUSLY look into HVLP
Since you are already using Chromata, get the Glamour II and an HVLP setup.
Tried and true thats my proven combo.
*Using a Krylon or Kamar can is just a beginner mistake, sure you can do it but its gonna cost you waaaay more and isnt going to give you the proper coverage.
(not to mention archival properties are seriously questionable)
*rolling is a waste of product w/ less control and a downright pain...
Talk with anyone using HVLP with any water based product and they will confirm this same info.
