I've got both and the only difference I notice is the lack of the bottom piece on the Clearview.
Does the Clearview have the protective coating as does the OEM?
Believe all Honda OE shields are polycarbonate with coating, Clearview and most aftermarket are Lucite and have no coating. Lucite never has a coating.
That's my understanding also, different plastic and no coating on the Clearview. But, like I said, the only difference I "notice" is the bottom piece missing, other than that, no noticeable diff.
