First time in the shed for over a month, just got back from an extended holiday in the USA.
Fiddled with Oshkosh purchases for a while.
As mentioned previously, my Aeropoxy arrived with the hardener in a crystallised state. Put all my tins in a Fowlers Vacola food steriliser at 140 degrees F for an hour, and it appears to be completely runny. Left it there for another hour and let it cool. Later it was still crystal free, so put back in the epoxy heater.
