Hello - I have already used the EM 6000 on a bedroom furniture project and it performed very well. I used an HVLP sprayer to apply the product (satin) finish. I now will be making cabinets for my laundry room using Baltic birch plywood. I intend to also spray this project. Which is the better product for this project EM6000 or EM7000 series? (spray-ability, hardness of finish, durability of finish)
