My epoxy says 8-14 hours at 23c. It’s very rarely 23c in my garage. Was hanging around in the mid 20s sometimes. I gave it maybe 17 hours, sometimes 24 hours before guide coat and flatting. I’ll bet I didn’t leave it long enough before flatting. I’m now seeing how it would carry on shrinking after I’d guide coated. I’ll be sure to leave the last panel, the bumper for days before I guide coat.whatever the tech sheet says the full cure time is , after that it shouldnt shrink any further
