Well, my paint finally came in to Home Depot two days ago. I had ordered the Rustoleum Stop Rust Gloss Harbor Blue - almost identical to the factory light blue on the Duster.
I rolled on the first coat on the trunk lid last night. It rolled out fairly smoothly. There were some small bubbles, but as suggested, I dragged the roller over the a second time. Just the weight of the roller flattened the bubbles. All in all, the first coat looks fairly smooth as is, although it is very thin. Tonight I'll be adding a second coat. I'll post picutres when I get a few coats on and have done some wet sanding.
I noticed there were two types/brands of foam rollers at Home Depot, I went with the white foam rollers as opposed to the cheaper yellow rollers. There was definitely a difference in density and weight between the two.
