Another vote for Aileens Tack it over and Over -- I water it down about with abour 1/4 water to 3/4 glue and dab a thin coat on. Let it dry then stamp - works great for me. But cutting it with water really made a difference.
I wanted the images on the back of the stamps and this has eliminated all my issues.
