Using the combined wisdom here I'm going to remove the safety glass from an RCA round color tube. Being this is not the sticky agent, I will use the clothespin method. I was able to remove some of the material from the edges to make room for the "shims" Hand applied only till snug with equal pressure all around. The CRT is face up in the south Florida sun and I will check it every half hour or so and look for the "fingers" and attempt to keep an equal pressure.
This is out of a CTC-16 of another VK member
