Don't know. I use Jotun Seaguardian when I can get it and their
Seaforce 30 if I can't. Both are commercial 'fleet' use eroding

thinners.

Trivia warning.

If the container is intended for chemists, it will be labled " xylenes
", as there are three arrangements of the three methyl groups on the
ring. Three adjacent, two, and none. Ortho, para, and meta. You cannot
separate them for any reasonable ammount of money, but you might be
able to synthesize one or the other. I never took organic, but I read
the book.
