Since I got some good advice here awhile back I have been signing my work with an extra fine point permanent marker. Then I spray with lacquer.
This worked every time, but recently the ink started running and flaring. This has been true with both Rust-oleum and Mohawk Pre-cat. In these photos, the wood was turned about 5 months ago and the ink was allowed to dry for over an hour.
Any recommendations? As a temporary solution I can sign on light wood with pencil, followed by lacquer spray.
