Yes! I also used glyphosate to kill things growing in and around my sidewalk, driveway, steps, and curb. I've also used a propane torch for the same purposes, but it requires more effort and cannot be applied quite so selectively. It works, though, and is a good choice for anyone who would rather use a petroleum product than an herbicide.

I looked up the product you mentioned and you're right -- it does look like deodorant! It's a gel that contains glyphosate and isopropylamine salt. Neat!
