About MEK--you still may have trouble finding it, and I'll grant that Carol's Friend Don knows more about it than I do, but--twenty-some years ago, we kept a bottle of it in the shop. It had an applicator brush built into the lid, and we used it to glue automotive air conditioning ducts and dash louver assemblies. Now, I didn't snort it or drink it or bathe in it or take a propane torch to it, but Don's post does strike me as excessively alarmist. Treat it with reasonable care, sure, but I wouldn't be afraid to use it.
