Tintypes were sealed with a Alcohol Lacquer. Perhaps you can do the same
with a dag. This requires the lacquer and tintype to be at 100 degrees F or
a little higher. It is a learned technique because if done wrong the finish
can be mottled, not what you want.
Sandy is correct when he points out that epoxy will yellow and maybe fog
with exposure to UV.
What is wrong with sealing them between glass? You are straining at a
problem that has been solved for over 150 years.
