Good for you Lynne. That's exactly right. I'm not sure if the Krylon has been tested with the PAT or not but most all of the overcoats will yellow and crack over time. I'm not sure about off-gassing.

It seems to me that if you use it on photos, you are violating one of the tenets of archiving: Never do what you can not undo. Lynne F.

A relative sent me an article where the author recommends using this spray on photos to protect them. I'm including the article text here, although I have no idea where this article might have appeared or who wrote it. I'm dubious, but admit I have never heard of the product before. Hopefully some knowledgeable conservator can clue me in on the use and/or misuse...thank you.
