47-55.1 High build body work question

[rnrdthefox]

As I type this, I realize this might belong in the paint section, but I think this area gets more traffic.

Anyway, my question is about maintaining the details (lines, features, letters, etc) when using high-build. As an example, my tailgate is new from Mar-K and I'm thinking about taping off the letters and feather the edges so there isn't a line. Would this be poor technique to (try to) ensure I keep crisp lines?

Is it customary to use it on all sides of the door? I'm tempted to spray everything and take the time to sand it all down.

I'm using Evercoat super build if that matters. I hear it's a little harder to sand.

Thanks
