Reply To: Wood case and miking
Welcome to the forum Gianluca, great pics and nice work, thanks for sharing. You can use marine, spar or polyurethane varnish 3-4 light coats should do the trick. Once the varnish is completely cured it is safe. I would not use a wood treatment like Thompson water sealer, also use stainless steel screws if possible as rust can build up with regular metal screws with time.
