5600 is a very good reflective. Hard to install over indentations in fenders, and pretac is a nightmare. But it sticks. Problem here, I see, is cheap laminate over excellent film. The laminate would fail before the reflective does. I don't use the Edge sealer pen. Does not apply enough clear, and takes toooo long to apply. I use a lettering quil with one shot clear. I can apply the right amount and it's fast. I had a problem with edge wrapping aq door with Coburn Imitation Gold around door edges. It would lift because it can't take a 180 degree bend. So I sealed it with a brush and One Shot clear and it solved the problem.
