MapProof adds water-repellency to paper maps and charts which helps to maintain strength and durability in wet conditions. The easy wipe-on application dries rapidly and smoothly. One bottle is sufficient for 6 or more average maps. Treated maps are still easy to write on.
Impressive! by Christopher Fairall
I used Nikwax to waterproof several of my maps. I was impressed with how easy it was to use and what a great job it did on my maps.
