Hi Steve,

maybe you just want to clean sigs using one of the import/export options.

*--import-options parameters*

   This is a space or comma delimited string that gives options for importing
   keys. Options can be prepended with a `no-' to give the opposite meaning.
   The options are:

   import-local-sigs
     Allow importing key signatures marked as "local". This is not generally
     useful unless a shared keyring scheme is being used. Defaults to no.

   repair-pks-subkey-bug
     During import, attempt to repair the damage caused by the PKS keyserver
     bug (pre v. 0.9.6) that mangles keys with multiple subkeys. Note that
     this cannot completely repair the damaged key as some crucial data is
     removed by the keyserver, but it does at least give you back one subkey.
     Defaults to no for regular --import and to yes for keyserver --recv-keys.

   merge-only
     During import, allow key updates to existing keys, but do not allow any
     new keys to be imported. Defaults to no.

   import-clean
     After import, compact (remove all signatures except the self-signature)
     any user IDs from the new key that are not usable. Then, remove any
     signatures from the new key that are not usable. This includes signatures
     that were issued by keys that are not present on the keyring. This option
     is the same as running the --edit-key command "clean" after import.
     Defaults to no.

   import-minimal
     Import the smallest key possible. This removes all signatures except the
     most recent self-signature on each user ID. This option is the same as
     running the --edit-key command "minimize" after import. Defaults to no.

*--export-options parameters*

   This is a space or comma delimited string that gives options for exporting
   keys. Options can be prepended with a `no-' to give the opposite meaning.
   The options are:

   export-local-sigs
     Allow exporting key signatures marked as "local". This is not generally
     useful unless a shared keyring scheme is being used. Defaults to no.

   export-attributes
     Include attribute user IDs (photo IDs) while exporting. This is useful to
     export keys if they are going to be used by an OpenPGP program that does
     not accept attribute user IDs. Defaults to yes.

   export-sensitive-revkeys
     Include designated revoker information that was marked as "sensitive".
     Defaults to no.

   export-reset-subkey-passwd
     When using the --export-secret-subkeys command, this option resets the
     passphrases for all exported subkeys to empty. This is useful when the
     exported subkey is to be used on an unattended machine where a passphrase
     doesn't necessarily make sense. Defaults to no.

   export-clean
     Compact (remove all signatures from) user IDs on the key being exported
     if the user IDs are not usable. Also, do not export any signatures that
     are not usable. This includes signatures that were issued by keys that
     are not present on the keyring. This option is the same as running the
     --edit-key command "clean" before export except that the local copy of
     the key is not modified. Defaults to no.

   export-minimal
     Export the smallest key possible. This removes all signatures except the
     most recent self-signature on each user ID. This option is the same as
     running the --edit-key command "minimize" before export except that the
     local copy of the key is not modified. Defaults to no.
