To be honest all these hardners and paints aren't given the respect that they are due.
Very true. I mixed a small amount of WEST epoxy only the other day to join some teak boards - it was only around a quarter of a jam jar and I was very careful to use the correct ration - I had however forgotten that fast epoxy in even small volumes can produce a violent thermic reaction - the pot had to be dumped very quickly as it frothed, gave out copious amounts of noxious smoke and became very hot! It is not cheap stuff so was a sorry waste of a pot of good epoxy - oh well.
(Sorry for the slight thread drift).
BTW having used a range of paints for cars, boats and wood (and even a little on aircraft although I have always managed to avoid them pretty much so far) I still think there is no substitute for two pack epoxy type paints they are so hard wearing, produce an amazing finish (albeit with a little work) and seem to last forever (although a stable base is vital).
