Hi Hamish - I'm curious as to the registration system that you use. I've been
doing gum for about six months now so I'm a relative beginner. I've used several
different registration methods but none have worked so well that I would
confidently make 6 or more coats. Usually I'm holding my breath for the second
coat and when that registers correctly I really get reluctant to hazard a third
coat.
