Not sure. I got the info from Klass Act from this thread he made. Thread also has some interesting dialogue (anti-insect as tire dressing)
KENOTEK now available on AG!
Tip for you, Desertnate: When shopping for products, as you're doing your "search by brand" - keep an eye out for brand specific sales. They usually don't get announced, but that's how I tend to save money. When a brand/product is on sale, and buy that DURING a sale, it's like a double sale. You're welcome.
