Here's what I did with my PC 9. I used monocote trim (6 in X 36 in) purchased at my LHS. It's not very expensive and has a sticky side that is protected with paper backing that must be removed. I just cut it in the shape I needed with a razor knife (or razor blade) removed the protective paper backing and stuck it to the surface after I had cleaned the surface I was applying it to with alcohol. I think you can use windex window cleaner, sprayed on the surface, to keep the trim from sticking until you have it positioned where you want it, then use a credit card to squeegy out any bubbles and windex cleaner from between the two surfaces. Let it sit over night for the windex to dry and the adhesive on the trim to attach to the covering of your airplane.

You might want to be a bit more aggressive by using a larger pattern than I did as a larger pattern would be even more noticeable from a distance.

As for the tape I use to cover the hinge lines on the control surface, it's much like clear Scotch tape, but is somewhat streatchy. I think it's made by Dubro and is "hinge tape" for foamy EP models, and is about 1 inch wide. You can also use the trim monocote I spoke of earlier as well by matching with the color used on the control surfaces. I just find the hinge tape easier to work with.
