I’ll tell you that G-05 is as bitter as can be. Had some clear liquid on my garage floor and wasn’t sure if it was antifreeze that had leaked out of a bottle, or water that leaked from the side trunk drains of my w123. Put a little on my finger and touched it to my tongue. I could taste the bitter for the rest of the day.

Generally I’d never partake in a taste test to determine a chemical, but I wanted to see if there was bitterant in G-05. Sure was!!!
