Dale: I suspect that you would be happy with either. Meguir's is a little less expensive and more readily available locally, but then Zymol, IS the official WAX of the BMW DIGEST guessing from the number of posts containing the words "ZYMOL, WAX, STREAKS, SWIRLS, BIRD POOP, etc". You pays your money and picks your poison so to speak. I use Meguir's. Happy Bimmering, Bob
