Painting with a paint roller.

Its not so much how the paint is put on sprayed, roller, brush or mop.
Most sand and buff paint before calling it done these days anyhow.
Some paints are gummy and don't sand or buff well. Others dry harder and do shine polish up nice.
Any paint can be applied. But....
If I was going to roller paint a car I would test the paint for ease of the sand and buff process.
