No Iso anymore, just soap and water in the ultrsonic for about 10 min. Blow dry and UV box for 2 to 4 hrs. If the item is flat i flip it about every hr. I leave the base on rings for curing so they stand up and get cured from all sides at same time (using solar turn table in double fingernail boxes with feet added. Use pull out bottom from on nail box as reflector "lid". leave opening for air to circulate or may get too hot (possible fire hazard).
