Well, I'm thinking that you could get a wand attachment for your spray gun which you'd insert through that little rubber plug directly in the middle and below the cowl vents. I haven't looked into this yet, but I'm assuming that's how the pros reach areas inaccessible with a regular spray gun.
I sandblasted the area under those cowl vents, so I'm gonna HAVE to find a way of spraying that area.
