I used a sponge-brush to apply the product to front and back of the open spread in a National Geographic magazine. According to what I have read, this is one of the few publications which will work because of its particular ink and paper. Some say it must be an issue published within the last ten years.
I was glad I was wearing gloves, because almost immediately some of the black ink began to break down, and it would have been almost impossible not to touch it and get messy.
When the pages were wet, I closed the magazine and waited for about thirty minutes. Waiting much longer may have caused the pages to stick together. After locating my pages, I used a heat gun to dry them. Some people hang them to dry, clothesline fashion.
