NiVRaM:

I think many posts here reflect a genuine skepticism about the number and quality of warning labels that have exploded in consumer products ranging from alcohol to McDonald's coffee (Careful. It's Hot!). California is an early adopter of warnings on anything that appears to be harmful, even if it took 200 times the recommended maximum daily amount over weeks/months to produce a harmful effect in mice. (Mice, BTW, have very little explicit corollary with humans.) Attorneys, and the litigation they bring, are another reason for much of these warnings, good or bad they may be. (Why do we need warnings and instruction manuals stuck to ladders? Why do we need warnings on McDonald's coffee cups?)

The absurd and the unknown both illicit humour. Such was the case here. If you really are interested to find out more about your risk, try going to http://www.msds.com/ and enter "Plaid" in the "Manufacturer" search window. Next, click on "Get All MSDS" to the right of "Plaid Enterprises". Next, click on "Folkart Acrylic Matte Sealer" to read about all the nasties contained within. You will need JAVA installed to read the PDF, as well as Adobe Acrobat Reader. Both are free. I don't have Java installed so I can't tell you what the PDF says.

Alternately, you can call, write or email Plaid Enterprises (or whomever makes the stuff you want to know about) and ask for the Material Safety Data Sheet (MSDS) which they are required to have for any appropriately harmful chemical they utilize in the manufacture of their product. If still in doubt, call your local health department, talk with your physician, a friendly and knowledgeable biochemist or don't use the product at all.

Hope this helps. Good Luck.
