Review (4/5): great product
Works just as it should. If you want movie quality effects you'll need an airbrush. As long as you follow the directions and put the pre latex lotion on your skin you shouldn't have any problems. (Shave anywhere you are going to put this product. You may think... "hey I don't have hair on my ribs" Yes you do and you won't miss them if you take the time to shave first.)
I'd suggest an acrylic paint brush for applying this product assuming you don't have an air brush. Use several fairly thin layers to build it up. If the latex is too thin it is more difficult to remove. If you want to go faster use a hair dryer while you are applying the latex.
