Seam sealer set up time... ever???? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I used the 3M seam sealer (not the mixed epoxy, just the caulk tube version) - let it set for 24 hours (says it's ready to paint in 40 minutes...). Touched up a few areas - sanded a bit here and there and did a little more skimming to make it nice. I then waited ANOTHER day and primed/painted - 7 days later... LOOKS fantastic - FEELS "mushy". The paint feels tacky - almost like you could leave a finger print in it. 10 days later, out of my shop now but under a covered pole barn, it feels firmer but like a fingernail would dent it. Just curious if anyone else has seen this or might know the issue.

I ADDED SOME PICS AT THE END
