Hi All,  I am on my second sample bottle of PVC-E glue.  I was able
to get a whole quart "sample" bottle directly from National Casein
by simply requesting it from them.

Because I am a part time rebuilder/hobbyist, I called them, explained
who I was and asked for a sample to test in my various applications.
National Casein was more than happy to send me a free "sample".  I have
been using it for several years now.
