yes i have had it happen. it's due to having too much flex coat rod epoxy in a small container. the chemical reaction and curing after mixing is quicker due to the small container and the large volume of epoxy - say over 15 cc's.
resolution - prepare everything you need to do to the rod first - bushings, spined the blank if you want, scuff the blank and seat, locate the placement of the seat, have your epoxy application tool ready, etc. now, create an aluminum foil tray to spread out your epoxy onto. it should be fairly flat and a few inches wide in each direction. after mixing, pour epoxy onto that aluminum tray and apply. you will have much more application time now.
