Well that didn't take as long as I expected. Just removed some of the cover tension springs and pulled the pool cover back from a corner to get a peek for the camera. I believe it's caulking. The gap is about 1/4" at the minimum to 1/2" in some spots. It's not grout, like the tile grout, as I can stick a finger nail partially into it, it's chalky and has some flexibility to it. I've attached two pictures for reference. Let me know what you think. Thanks
