I had a similar situation about five years ago with base coat/clear coat. I had sprayed the vehicle in September in 65°dry weather, required for spraying but then we had a cool spell. For the next week, I’d park it in the garage then take it back out in the day so the sun could help cure it. I buffed it out after two weeks and it looked fabulous but you could dent/scratch it with your nails. I let the vehicle sit in the garage over the winter until the spring when it warmed up and let it sit in the sun. A few days under the sun in 70° weather, it finally hardened.
