If the result you want is only obtainable from the Platine paper and that means
coating twice, fine. But my pocket says that it prefers a single coat. I use 1
ml for a 10 x 8 or 0.25 of a drop per square inch at 20 drops per ml, but I
usually up the amount to 1.2 ml to ensure even coverage. That is quite a bit
easier on the pocket.
