I have used the glue on test pieces. I started from the center and squiggled to the edge. I used a plastic paint edger to spread it a little. Then took it to my drying rack and turned the fan on it. Laid it across a couple bars so it wouldn't be so weighty. I try everything out on my uglier pieces then donate to animal rescue shelters. That way the pieces aren't wasted.
Good way to practice FMQing.
