You can also thin down the sauce to where it just starts to run off the back of a spoon. Then you can spoon it on and it will even itself out, kind of like paint.
Be sure to go in and get the tendons and veins from the underside of the thigh meat. I use a small pair of hemostats that I bought at Harbor Freight to reach in there and get them. Blood in the meat will get you DQ'd.
Also, for skin 'scraping', I use a 8 inch flexible boning knife that I bend into the fat and sort of slice it off. Takes a little practice but you can get those skins super clean that way without wrecking them. It also helps if they're a little cold when you do it.
