[Elecraft] Sand/scrape mechanical connection points on EC2 case?

[Ken Rice]

Dear Elecrafters,

Do I need to sand or scrape the points where the EC2 panels join together so
that the whole case forms a continuous Faraday cage?

This seems to be done in the K2's case, but the EC2 case doesn't have the
bare metal masked areas seen on the K2 case.

What do you think?

Thanks and 73,
