Brian- My LHS carries it. I have used the bottle and brushed mine on. It's kind of like a liquid putty and you can thin it and shoot it if you choose but I prefer to put it right where I want to put it with a small paint brush, a cotton swab or Tamiya swab straight from the bottle. It dries quickly, adhesion is good and it sands easily (work with fine-very fine grit). It's neat stuff when you have those seam smoothing problems, pinholes or little imperfections to deal with.
