I don't know? I find it difficult because as you spray everything becomes a giant white out! Hard to see the wet edge so more orange peel and/or dry spots. Even with holding a light in one hand it's very hard to see what needs to be seen.
I only use a home made booth so more over spray in the air than in a commercial setup and that destroys your ability to see differences since everything is white.
