I too use Rejex on my car (I don't have a plane yet

) and love it. Like the others have said, it makes removing bugs, tar, brake dust, or any other gooey stuff extremely easy. Simply put, nothing sticks to it and it lasts a long time. Having said that, there are
NO UV inhibitors in it and it says so right on the bottle. What it does say is that it has a "highly refractive index" and it reflects most harmful rays. If your plane is going to be sitting in the sun, I would use a product (i.e wax) that offers better UV protection. Hope this helps.
