[BRENT in 10-uh-C]

To be honest, if you are using a 2 stage urethane, we find it really does not matter. We almost always come back the following day and pull the tape & paper. Old habits die hard but paints today are much different than what was used 10-20 years ago.

FWIW, the biggest reason why people used to do that method was to hide the fact that the job was poorly prepped where the substrate surface was not properly toothed to have proper topcoat adhesion.
