DR1Driver has the best solution, I also do it that way with 30 minute or longer cure time epoxy. A little heat from the heat gun after application and the epoxy flows out smoothly, gets into the most minute spaces and cures well. I've seen many cases where alcohol mixed into the epoxy causes the problems that Piper28 has. Epoxy doesn't dry, it chemically cures and any water (isopropyl can have as much as 50% water in it) interupts or prevents this cure taking place.
