I don't know if you all even care about these paints but there's so little information out there, I thought it might be good to give you my observations about them.
First, they are an oil paint although it's a synthetic oil so I guess they are correctly labeled as an oil paint. I know there's been some controversy about that.
To me, they handle like the WSO's only better in some regards. It's great to be able to lay down your brush and leave out your palette when you get interrupted. They certainly fit my way of painting and while they do have some quirks, I'm liking them more and more.
I think it's somewhat misleading to say they never dry. Well, I don't know about actually drying, but if you paint in thin layers as I do, the gessoed support does absorb the oil or something so the painting feels dry with only a couple of layers applied. It's also difficult to impossible to blend when that happens. I don't know about painting more impasto, that's something I'll try as soon as I get some more supports prepared or get more canvases.
I do know I got some of the paint on my shirt this morning and it feels dry and hard. I'm getting ready to wash it to see if the paint comes out. That would be another plus in my book if it does because I'm a somewhat messy painter and don't have many clothes left without paint stains!
Also, I've discovered that if you cut some paper towels into eighths, the sections are just right for wiping the paint off a palette knife or wiping a brush between colors.
I keep a little cap full of the 91% alcohol and use it to further clean my brushes between colors. It really doesn't take much after wiping well with a paper towel. Also, a tiny bit mixed into the paint will thin it out enough to make a thin line for instance.
There really is no odor during painting except for the alcohol.
I use a disposable paper palette during painting for mixing but use an old metal pastel pencil case to lay out the paints and to store between painting sessions. It's a little over 7 inches square and too small for mixing paint but perfect for keeping it covered. I bought a glass microwave turntable plate in a thrift store but it's kind of bulky and heavy while the paper palette is easily moved or held when I need it. If I have leftover mixed paint, I can either save it in my metal case, throw it away or add it to my jar of leftover paint which I use for painting shadows or toning down some colors. It just depends on how much is left and whether I feel I'll ever use that color again.
The paint is expensive to buy but is pretty cost effective since you can use almost all that you have. There's very little waste.
If anyone has any questions, just ask.
