For me I would like to coat the paper in advance. What should be the longest time I can store the paper until use? Also for 8 x 10 negs I am cutting the paper to 8.5 x 11 and mixing 2ml (total solution) per paper. I'd like to mix up 20ml for 10 papers (at 2ml per paper). Any reason why I should not? I like to plan a whole day for printing and making the paper that day just makes it longer.

Can I microwave tests prints like conventional silver paper?
