My VIS has been flawless, although it is not a DD. And it has seen some serious heat conditions on very hot summer days over the 10 years I have had it. No hood pins, and no issues at 130 MPH when I was Data Logging
I did remove some of the underside vent covers (on the side's if I remember), and painted the underside. Just good old wax and detail spray on the finish, which was - and still is - excellent.
