Adding to the dogpile-used a roller once, never again. Were I tasked with your project, I'd investigate HVLP spray. The low pressure practically eliminates 'bounce back' and reduces the need to get crazy with masking.
You can rent these units-practice outside to get a feel for the tool, and then go for it.
