I've mixed Xtol three times now, and it always hard to get it to go into solution.
I warm up distilled water to about 85-90 degrees, and s l o w l y add part A, then part B, and finally add enough distilled water to make a liter solution. It takes about ten to fifteen minutes to get most of it dissolved. I get tired of waiting after about twenty minutes and pour it into a storage container, while leaving a few crystals behind in the graduated cylinder.
Anybody have similar problems, or am I doing something wrong?
