Test it on a little corner or a side window. The type of perspex on your aircraft might be one of the non-cloudy types.
It can, however, be bit of a faff to apply properly. You are meant to rub it in relatively vigorously so that it effectively penetrates the top layer of glass/perspex. If you just apply it lightly, it will be washed off in the first couple of showers (believe it or not!)
