I'm planning to apply a TruOil finish to my spruce top. When using shellac I apply sellotape to the bridge area, polish the bridge and top separately, then remove the sellotape and glue the bridge in place. That's my preferred approach to the planned oil finish, but I'm wondering whether the oil will penetrate underneath the sellotape and then cause problems with the gluing - it is oil, after all. Safer to glue the bridge on first, then finish the top and bridge together? Or can I use the sellotape method?
