Awesome Bruce, very helpful.
I would add that I personally use Filmoplast P90 tape (since I'm opposed to linenbacking) and it has worked great over the years.
Also, any recommendations to remove tape residue on paper? I used to buy those adhesive NYC subway posters, and a few of them "licked" when it got too hot at a house I was renting years ago. They are all sticky at the border. Would you recommend bestine to remove the extra glue? It's a little like what you mentioned, but a little different.
Someone supposedly "in the know" told me to use lighter fluid years ago, but it doesn't work.
