I can't speak for the Hot Sauce but Uni-butter I can. Last year I was fishing in the south bay, and I had a 4" swim bait that I was going to use and I put the butter on it. As I let the bait sink so I could real in the other line the bait with butter gets hammered, I didn't even have to jig the bait. Released the fish and casted out again, WHAM! This when on for about 20 minutes. The second rod I had in the water had the same bait on and was roughly in the same area but did not have UniButter on it. The bait with the Unibutter was getting nailed. Think what you will but the butter gets you bit, and the fish hang on.
This is one of the 10 fish I caught in that 20 minutes. You can see the Unibutter in the picture also.
