I feel compelled to report ... the more we use the Gripper , the more we like it as a PRIMER ...
but NOT as a Glue for attaching canvas... Still some signs of skin lifting even after a careful application of the Gripper to both sides

... It could be the extremely thick canvas I’m using ...

Haven’t tried it with a Thinner canvas .... Just sayin’ ...
I am waiting to see if the painted canvas shrinks in the heat , and
magically re sticks itself down ...

But we may have to inject some T2 under the bubbles to take care of the problem ... Thinking since we have the deep kerf slots still exposed , i could go in from inside the trailer and punch through the thin area between the kerfs to inject the glue .... no holes in the outside ...
Ps. Copied to the Glue section too , just so nobody misses it ...
