shortcircuit...

Not providing you with an MSDS is potentially a very serious issue. Having said that...

If you ask for an MSDS and one is not provided, there is a good chance that you can get one yourself from the lacquer manufacturer on their website.

Not promising I can find it, but, if you post the exact name of the product and the manufacturer, I can probably locate one for you.

You can also search a large database that is maintained by the University of Vermont. The website address is: http://hazard.com/msds/index.php
