Sorry about weighing in on Garfields so late. - computer in for repairs- brain next- The man I did my apprenticeship with, 25 years ago, told me that his father, from whom he learned to tune, was a friend of Mr. Garfield (who's first name was Bill, I believe). He told me that Garfield experimented with glycerin and wood alcohol and after observing some improvement in pin torque, put the product on the market. Since glycerin and alcohol are both clear liquids, he would add a few drops of food coloring to each batch so it looked a little more convincing as a chemical product. Sometimes, he used blue but usually green. One time he got a complaint letter that accused him of sending out a weaker strength product that didn't work as well as his original formula. When he checked the batch, he had used less food coloring than previously, although the glycerin and alcohol were still at 50% each. That was when he began carefully measuring the coloring additives. When he decided that he was spending too much time with the product and away from his tuning, he sold the formula, possibly to Schaff but I don't know for sure, and they just sent out the colored glycerin with instructions to mix it with "completely denatured alcohol." My mentor and I used blue food coloring with the batches we made. Since Mr. Hager has passed away, I regrettably cannot reconfirm or clarify any of this, and now wish I had paid closer attention to his anecdotes. Since I was young and impatient, I can only hope that I am now older and patient; I've kind of given up on older and wiser. John Stroup
