This is great stuff for the money, and just great at any price. Benefits (to me, at least) are that it cleans up with water, so if I get this all over my hands and tying desk, it's easy to clean up. The stuff isn't runny as water, but it isn't quite as thick as epoxy (at least, not the epoxy that I've been mixing 50:50), I'd say leaning towards the epoxy side about two thirds between the two. It's still thick enough that when you place it, it doesn't go absorbing into the entire fly like thinned head cement would - though, if you really wanted to, I've been told you could thin this stuff with water (disclaimer, i've not personally done this, not sure how that would be first hand). I primarily use it for copper johns (the fly pattern) and similar flies, to get a more matte-finished shellback bubble, with no yellowing like epoxy, and only a little opaqueness that I find barely noticeable. No need for UV lights. Stuff has about a 15-20min working time, which is like forever compared to most stuff on the market, a real plus. The biggest plus is that it comes in 2 ounces - huge! - for just 8 or 9 bucks or so. A real steal. OK, so cons. The nozzle is like applying with a fire hose... it isn't focused enough, for my uses. I squirt a dab onto a post-it and work with a bodkin from there. You have enough of the stuff that I can justify doing that, for the price. Yup that's my con - just one. Strongly suggested product, and JS has the going price for the stuff, maybe even a little cheaper.
