PTIPTI Bookkeeper Spray - 32 Oz.

This works perfectly for preserving my family heirloom documents and papers. I just wish it weren't so expensive. The weight listed on the bottle includes the weight of the bottle, so keep in mind you're not getting 32 oz. of the liquid.

Very expensive, but as near as I can tell, the only game in town.

I purchased this product a few months ago because I wanted something to stop my concert tickets from fading. I was able to spray 40 tickets before the bottle ran out front and back size 5.3 ounces not 32 ounces like my review says, and I think that is alright for the price. I only give this product four stars and not five, because it leaves a white powdery residue on what you are trying to archive that may need to be wiped off if you spray too close. Careful not to use paper towel because that can scratch the coating off concert tickets or baseball cards. Use a microfiber cloth with water if hou have to only and ask me how I found that out.Well what can I say, the product was very worth it for indoor use. You have to pump air into the bottle because there is no solvent gas stored under pressure. That's why there is asboutely no smell or VOC's. I used it in a room with no windows for an hour straight and it's just magnesium oxide powder mixed in a neutral liquid. It also did not cause a negative reaction to any of my concert tickets. If you have 400 pages to archive, maybe this product isn't for you, but it served my purpose extremely well and would buy again.
