I discovered the same thing when I was replacing some rotted wood (what little I used) on my foamie project. I had to peel back the canvas, and the spackle came off in chunks. So much so that I had to peel back even more canvas and get it all out of there to improve adhesion.
Back to the original topic, I didn't use dowels to join panels, but I did use bamboo skewers every 10 inches and taped the seam while the gorilla glue dried. I laid the panels on their side and weighted them down with bricks while it dried. Four years later they're still strong.
