No sir. It a lot like others are talking about like the cavity wax but it dries harder and has excellent creeping characteristics. I've done tests with it and it will climb 4 inches up an aluminium can. I don't think it will hold up to an abrasive type salt test but for between seams that get sealed it is an excellent product or for interior work. And it wont keep leaking when it get hot. I use it along with this.
