Weird!! I was about to post the same question! I got told to firstly paint on a a thick layer in small circular movements then do the tip then the stress area and build it up but when I watched the NSI video it showed you to just paint on the first layer and kind of paint the rest on? I watch NAIO nail video on YouTube and she dose the same! But wouldn't this make the nail flat? I'm so confused?
Thats one of the reasons I posted this...I got myself into a youtube frenzy after seeing lots of different methods!
