Ah yes, I remember Hot Stuff CA... that was some good stuff!! Wish they still made it, I would definitely use it. lately, I've been using a CA that I get at my local Hobby Lobby. It's called Extreme Power, and it seems to be good stuff. $4.99 for 2 oz. bottles, thin, medium or thick. Been using it mostly because the Hobby Lobby is closer than the LHS is.
