I'm not a painting professional, and this work proves it. I was just making it up as I went along, but the results are good enough. I had three types of bronze spray paint to work with. After priming the barrels with acrylic primer using the air brush, I selected the paint can on the right since it seemed to have the best coverage and was dark enough. The one on the left had more clear varnish in it that pigment, and the one in the center was closer to gold than red bronze, but had good coverage. After spray painting 22 barrels of various sizes for the upper gun deck, a wash of brown and black diluted with thinner was used to further darken the barrels and bring out the details a bit.
Test sample each paint. I liked the one one the right the best. The center and right ones had visible metallic glitter in them, and the one on the left was drab and not very metallic, and had poor coverage with pigment compared to the others..

I already had some thinner polluted with brown paint, So I added two drops of black enamel and went with it for a wash.

Two barrels on the right have wash applied.

The barrels appear glossy, perhaps too much, but they'll work. The paint is still wet here, so the details look gloopy. After the paint dried, however, the paint coating thinned and the details became sharper.
