Decal is available right here from Pelican Parts

For the rear wing/spoiler I've tried both Back to Black and the inexpensive Vaseline treatment. Both work well although my impression was the vaseline seemed to last longer but took a bit more effort wiping it off. YMMV I wouldn't use glass cleaner for the wing.

Oh, the test for clean glass? Put a plastic baggie on your hand and run it over the glass, you'll feel the dirt you don't see. After using the Diamondite product totally smooth. Hvae you tried claying the glass?
