I recently completed a Venture 60 Kit and I'm a little worried about the gaps in some of my control surfaces. (see pics). That's a penny to give some scale. I used a Easy Hinge machine to cut the slots and pushed the surfaces together as closely as I could, but the gap remained. The gap is about half the thickness of a dime.

Should I cover the gap with monokote? Or should this be ok to fly with? It doesn't seem like the Monokote would adhere very well with the amount of movement it will be subjected to. I didn't hear any flutter over the weekend, but I haven't flown the plane really hard yet.
