Thats too bad Cal...thats one of the things you have to be careful with when sandblasting.  A lot of people use other media now that is a little more forgiving...plastics for example.  But even those can erase a serial number that is already light from years of abuse.  Just remember to remove the tags next time, and hey dont beat yourself up over it (if you were) IT HAPPENS!!! <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: -->
