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

I saw a review on them on YouTube they are about twenty bucks. They put them them up against a high dollar sprayer. My only problem is the paint is $100 so rattle can is looking better. Depending on how many cans it takes it could come out the same. I did find a paint shop that will paint it for $200. I would rather give it a go myself.
if I'm not mistaken and I'm about to go there myself. Right now LOL that Harbor Freight has some Mask to wear to paint with that are pre-sealed. I know you're not literally dying to paint your car. Of course I always encourage the give it a go angle myself. You end up with the experience at the very least good or bad and all the tools at half the price.
