I was at a Car show and Saw this 68 Camaro with the windshield mounted flush, like a new car and, to me, it looked awesome. It's a real clean look and eliminates the stainless molding and is replaced, by a black seal. The glass is silk screened around the inside edge to hide the adhesive, which is what the stainless did originally. I spoke to a Glass supplier, who manufactures glass and they liked the idea and said that they could produce such a glass and the seal easily, it's just a matter of demand..so I'm sure that demand would have an effect on cost, but the supplier said it shouldn't be much more than OE glass. So what do you guys think. Here's a link with some examples, Check it out.
