The author here appears to be confusing design patents with regular patents. A design patent covers the specific appearance of a product, functioning more like a trademark than a patent for an invention. The relevant matters here would be whether the appearance is similar enough to cause confusion, not whether anyone has ever used a wrap windshield before.
That being said, I do agree that they look nothing alike, so I would not expect this to be a very strong suit.
I believe that the convention on darklyrics is to either elide or replace with "[chorus]" all repetitions of the chorus after the first. A few spot checks seem to confirm this, but I can't find an official policy on it.
