Thanks, that's what I wanted to know. I possessed Gurney's book since the moment it came out and had pre-ordered months in advance, so I had it even before Amazon.de assumed it to release officially. ;)

Gurney wants you to work with oils, of course, which is impossible for me considering my living space. Well, at least I've got acrylics now that need a lot longer to dry... time to "get dirty". :D
