I think most people agree that it's better to do that.

I know it seems 'black magic' at first, but once you've done it & reflected a bit it's not so scary.

Shield all your cavities. Copper foil with an adhesive back & conductive paint are widely used & freely available. The foil can be a pain to work with, but you can solder to it eg to connect all your cavities. You need to use a number of coats of paint if you use that.

Don't forget the earth from the bridge or tailpiece.

If I had to recommend any one thing it would be to relax a bit do a deal of reading & practice & then do the job when you're happy about things.
