I use it straight from the bottle, move fast so the "line" is real thin. If there are any globs, I simply use the tip of the bottle to spread it out. I like to leave dry overnight. Takes only a few minutes to apply and you don't have to be perfect. I use diagonal lines about 4" apart. If there's a void in the line, I only fill it in if it's more than 4". I simply compare it to when I pinned with safety pins. That was only about every 6" and was only a lone spot. My thin sloppy lines give me a wonderful sandwich to work with.
