Well "PMF" does not itself specify the adhesive / paint type especially since Glidden Gripper is gone
so really the question is, what are / were your intentions there?
Might be worth just experimenting with different choices, use pull tests after curing.
One should be just using that primer as an adhesive for the canvas, never know might be great, and certainly should stick to itself.
If that works then a compatible outer paint should be easy to identify, a tough "porch paint" or for concrete, decks etc
Make sure very UV resistant
