Blop it is. I keep a batch mixed up at all times. Sadly this is the only unpainted window in the entire house and there are 140 windows total (!). I've got a whole blog and a podcast. I could bore you in a hot second, but I hope I wouldn't.
PM me for the info if you like, or if Admin is amenable, I can post it somewhere on this site. I think the blog is already in one of the forums IIRC.
