This is my 400mm 110v silicone heat made on my bed. Suddenly nothing would stick toy bed any more, regardless of temp, offset, and adhesion assistance agents. I finally looked at the center of the bed was puffy. I was able to slide a ruler in between the aluminum bed and the pad. It took a bit of elbow grease to pull off the edges. Dunno how close to disaster I was but it's a little too close for comfort. It never overheated in all my use and the thermal fuse is still in tact but the scorch mark is still disturbing.

Exactly. I don't know the expected life span of 3m 468mp but apparently I exceeded it in my environment and duty cycle. I'm still working on getting the residue off of the bed however, and I can say that where it stuck, and did not fail, it did an excellent job, even pulling off bits of silicone with the glue.
