Trim

You don't normally go to this extreme when painting baseboards but this custom built house had so much trim that we completely masked the hardwood flooring off to spray the baseboards and all the other trim at the same time. 

Preparing for spaying like this was a ton of work but it produced silk smooth results and reduced at least 80 hours labour in comparison to traditional brush and roll.

Painting Trim

Steady / "hand eye coordination" enables painters to exceed in both speed and how paint flows. Today's paint dries fast, therefore, if you are able to cut lines straight before paint starts to "set", it always has a nicer edge and looks better to tape lines.
