New fiberglass hood: Has anyone ever had success with flat black rattle cans?

Get they harbor freight gun and practice shooting the primer on the top part of the hood (easier to sand your mistakes) and you're going to be sanding it anyways. Or spray the underside first since it won't be as noticeable. $10.00 bucks with a coupon and not bad reviews.

Worst case you make a mistake and have to sand it and re-shoot it. Not a big deal
