Everything will be fine. You've gone down the right road by having an instructor. lownslo is right on about the Ultracote. It works a lot better than Monocote for a lot of reasons.

I know it is your pride and joy now, but after a few months of flying it will have a few dings in it and you will be getting bolder with your flying. Soon you will not care and you will be beating the tar out of it with some wild flying. This is when the real fun begins. When you are not afraid to ding it a little, it's a lot more fun to fly it.
