|Coat of primer.|
The thing is a beast to drag out of the hangar, but managed to "walk" it out and put on a tarp to paint.
First a layer of primer - the pain said it wasn't needed, but couldn't hurt anyway. Then I sprayed it with a 'textured' black paint that gives it a smooth but bumpy texture. It turned out nice! The second photo doesn't show the color too well since the sun was behind a tree and was getting dark.
