'Too darn hot'!

I think we can all feel your pain here..... the only paint suitable for this weather is oil paint, the traditional stuff probably rather than water soluble, because it won't dry and die on you. It's a pity, because you had a good composition here and at one point it probably looked as if it was going well - but I can tell where it started going wrong.... happens to all of us; maybe a water-mister would have helped, but only if you like to paint wet in wet (and even then, an absorbent paper, plus this heat, would have defied your best intentions. Still, live and learn, eh?

Oh dear Stephen, never mind as Robert said its just one of those that rather got away, every now and then it happens !
