No, it is a relatively flexible film, more so than nitrocellulose lacquer. >What about clairity? Equal to the solvent-based stuff. >Are piano factories using water based lacquer on their lacquered parts? Dunno, but they will be if they're not already. Seems I see alot of polyester finishes, though. I do know of at least one major body shop (auto) here, the biggest in town, spraying water-based urethanes in their scheme of finish work. >Of course it cannot be compatable with solvent based lacquers...or is it? I wouldn't go so far as to say you can mix and match to your heart's delight, but I have many times used Mohawk's solvent-based toners under it with no problems whatsoever, and if the water-based material has cured a week you can topcoat it with solvent-based lacquer with no problem, if you really wanted to. >I always rub down but spray a final 50/50 coat as the finish coat. Can this be done with water based lacquer? Not that I'm aware of, and I would think not. There is, of course, a slight alteration of working method required when one moves from solvent to water, and this would be a step that would change. The final topcoat would require slightly more rubbing out than that of nitro, in my experience. The differences are not so great as to be substantial, though. >Once again, my initial investigation into this type lacquer indicated it would not > hold up as well as solvent based lacquers. Has this changed or do you think > I received incorrect infomation? Depends how long ago you received this information, and who you received it from. People who have never even used water-based lacquer seem to have some pretty hard-held beliefs about its performance. And there have been some pretty lame water-based finishing materials in the marketplace, to be sure, in the past, but the advances of the past 5 years have been significant. > I am open to new methods.

Tommy, I am in no way trying to convince you to change your methods, do what works for you. If you are interested in checking out the new materials, I wouldn't be surprised if they might offer trial quarts for the professional finisher wanting to 'take a test drive'. It does take a slight adjustment, though in your spraying methods, so some initial tinkering will be necessary. If you got serious about possibly changing over, I would suggest you talk to some finishers down there using water-based to shorten the learning curve.
