make sure you have primer ready after you are done cutting to primer the newly exposed metal. I used rustoleum. I realize my hole is not perfect, I didn't really care, my scoop is functional to help keep the engine bay cooler. I then took some weather strip adhesive in yellow and glued door edge guard to the newly exposed surface to protect it and me. Those edges were sharp. I threw away the hood baffle, my Vx is loud anyway, so I don't care about sound deadening anything. It came out great, about 1 hour or so, less than a hundred bucks. I would put myself at a medium skill level. The rocksliders install was way harder and labor intensive compared to this project.
