Fred, I must echo your point about Steinway's lacquer. I think far too many people, including instructors, talk too much about dilution and not enough about concentration of the final product. When I heard Eric talk about the details of the lacquer they use, it was a real eye-opener - explained a lot of the bad results I had seen people get with lacquer, and why I never liked it much before. I have to check your math, though. Most off-the-shelf lacquer is around 25% solids, + or - a few points, or roughly double Steinway's concentration. A 3:1 solution means 3/4 thinner and 1/4 lacquer, giving them a 3% solution. To get to the same concentration with our lacquer, it would need to be 1/8 lacquer (half as much) and 7/8 thinner, or 7:1 dilution. I'll mix at 6:1 or 8:1, depending on how big an effect I want. Just my 2 cents (or maybe 1 1/2) worth, Ken Z.
