Reply To: Paraloid B-72 and marking museum artifacts

Recently was a topic of Paraloid B-72. It is under the “White Ink” topic.
I was a curator for NPS, followed the numbering guidelines, and in a private setting continue to follow the guidelines. I only had issues if I failed to wait for proper drying. No real problems if you let the media dry. Hurrying the numbering process yields dissolving and smearing. Base coat, dry, number, dry, clear coat, dry. I like to let the base coat dry at least 8 hours, the number a couple.
