After checking out your link $$$!!!, Mr Smith would be better off asking local parts stores. Not chain stores but locally owned. A hood would take quite a bit, not something you would try with aerosol cans.
Properly applied, high quality spray paint in aerosol cans will do a good enough job. The alternative would be buying bulk paint, a several hundred dollar paint gun, and an oil-free compressor or appropriate oil filters for an oil lubricated compressor. That or going to a body shop to have them paint it for you. All auto paint is sprayed, the results from trying to brush it on would be unpleasant, to say the least.
Also, the first link, while more expensive than the second link, doesn't seem insane to me. Yeah, it's not $5/can Rust-Oleum, but it's much higher quality paint, plus for the pearl you need two basecoats plus the clearcoat. Most automotive paints besides pearl are single coat plus clearcoat, but pearl requires an extra coat. That's one of the reasons why if building a custom order new vehicle, pearl paint is something like a $1500-2500 upcharge over the other colors (I've priced out a couple of custom vehicles, and pearl paint is always
an upcharge over the normal colors, because it needs an extra coat other paint colors don't).
