In this photograph, you can see the one minor flaw in the aluminum radar. A tiny hairline wrinkle is visible where the vertical band has been welded on the inside. The glaring flash on my camera makes the flaw seem worse than it really is. This flaw is nearly invisible unless it is pointed out. I will be placing this weld seam at the back of the radar, so no one will ever see it anyway. Bead blasting, buffing, or painting would probably cover all traces of this seam.
