I don't know about the quilting, but I have just finished a t-shirt quilt top and there were a lot of that rubbery material on the logos. I did use an iron with a press cloth. The stabilizer was applied by pressing it on with a press cloth on top. Then I gave it a final press with the press cloth over the right side. Once it was done, I was giving the sashing a final press and forgot the cloth and tipped one of the logos and did a bit of melting, but thankfully, I caught it before it was very bad. The press cloth did work for me.
