Interesting – if that is 2 pack he’s using, he wont be feeling too good right now! I’ve used Warnecke and Bohm paint from tins like those, and they were definitely 2 pack!

Should he be using at least a face mask?
I dont think that in Scotland we could paint outside with a spray. Would you need no wind and low humidity and what about the surrounding ground would it not be covered in splatters of paint. I presume a proper vetilated paint tent is the best bet.
