Minor defects with Extruded Cut on curved surface?

Hey,

I am trying to create an extruded cut that follows the curvature of a cylindrical surface. First, I created a sketch of my cut and then I projected it onto the curved surface using Project Curve. Then I created a 3D sketch from the Projected Curve and performed an extruded cut from that.

However, I am getting these minor flaws in the cut that I am not sure how to solve. 

Any advice would be greatly appreciated.
