Occasionally I fantasize about painting the front door to my house in International Klein Blue. The binder of true IKB seems to be a polyvinyl acetate, so I wonder how well it would hold up for a semi-enclosed exterior application. Anyone have any idea? (The next question, of course, would then be sourcing that quantity of paint....)
