What Sticks to Coroplast?

I used eternabond on my corplast with mixed results. It seems that for eternabod to work well you need a fair amount of pressure on the joint when you install it. Not easily done on corplast in all places.

Next I tried scrimshield. That stuff made eternabond or gorilla tape look like cheap masking tape. I've never seen something with adhesive like scrimshield. once the adhesive touches the corplast (or itself or anything else) it's not going to move. that stuff is utterly amazing.
