I'm about to head for home out of my office so I'm in a hurry... I apologize if I double-answered either of your questions... My hood came pre-drilled for nozzles. I just pulled my stock ones off and swapped em' over. Took five seconds.
My hood has stayed in place without hoodpins for a few months now no problem but I want to install them anyway just so if I go out of town for a race, I don't get surprised by the officials saying, "Sorry bud... gotta' have hoodpins."
The VIS has a UV-protectant gel coating that can be waxed so no problems there.
TIME TO GO HOME!
