Thanks, Paul. I realized it's just the acid and base that's useful, but some vinegars are so... "polluted" with flavors and additives that I was looking for info if there was a brand to avoid. "Cheap", however, is good enough for me.
Timbuk, those panels really look like they were made for you bus! Thanks for sharing the pics. In the second image, are you in the painting stage?
Kinda looks like the bus is trying out for a zombie movie.
