https://www.amazon.com/Martin-Yale-...60046&sr=8-2I've used this for years on paper (in ISO compliant anti-static manufacturing environment), it works well and leaves no noticeable trace. Note: I have not sprayed it on stamps themselves and would not recommend spraying on the stamps or the sleeved page. Instead I would only spray on the glassine interleaving and allow it to dry. I would approach this as experimental (test, check, etc).
