depends on what brand of cf hood u buy as well too. seibon and vis doesnt need hood pins and are usually best fit, just a little adjusting on the hood latch and hinges and you're good to go. but like hulud said hoodpins are just to make sure your hood doesnt fly open and imo they are ugly as sh*t. and one other thing, when u put on the hood, align the holes up and dont force fit it in kuz u dont wanna strip the fiberglass thread in the hood.

what do u mean waves under the clear coat?
