Gorilla is available locally and works pretty good and has been my go to. I found some on Amazon by "cec corp" from our neighbors to the north (my new go to).

I've been impressed. Cost is better than most and it seems to cure about twice as fast as the Gorilla version. Which means I can go on to the next step quicker...
As long as you pre-fit the zim pieces, you'll have plenty of time for sliding around and fitting.
