I'd like to be able to do the light seal at the back hinge, the ones along the back, and the mirror foam. Isn't the hinge seal a different thickness from the ones along the back? Also, is the mirror foam a different type of foam? I do like the idea of using felt.

The seals buried in the channel along the length of the body aren't critical as light seals. The hinge seal is, though, and should be changed. I use the same foam for the mirror. Felt doesn't compress as readily as foam and can strain the hinge and put unnecessary pressure on the latch at the other end.
