It's a wise idea to seal your hinge gaps anyways, so I'm just using white monokote for the task which also ends up covering up the rehinging that I did on mine. The rehinging is not a big deal as I always run my slot machine through the slots anyways to assure they are the proper width, so there wasn't much to the fix on this plane. Overall it's been a very high quality kit and has had far less re-engineering than many of the other "ARF"s I've put together as of late.
