hmmm. Thanks for the replys.
In a way I would be suprised if it was solvent pop because it was a really warm day when I painted and I let it dry for atleaset 30 min between coats.
To be honest my airline filtration system is a bit slack, it only consists of a copper tube spiralled through a tub of water and a water trap. I was wondering about that "iso clumping" issue. Why is this never mentioned in paint defect guides and data sheets?
Do you think its the humidity in the booth or in the airline thats more important?
