You know, i think that I will impart this once and for all. I do not use foam. I use black yarn and it works great for most SLRs. You leave a bit of the old foam in place to provide stickiness and carefully start either the upper or lower channel from the hinge across to the door latch (about five or six inches). Tuck everything securely and maybe put a tiny bit or Elmer's glue on each end. You could also slightly put some glue on your fingers and gently wipe the yarn before inserting it into the channels.

For the hinge part of the door (about 1.5 inches) I use thin, self stick weatherstripping. The first time you close the door it should be mildly hard to do but not extremely hard. After a few closings it will be really a secure fit.

Tip: do not cut the yarn until you have laid it up to the door latch. Then, carefully cut it with either a sharp scissors or use a new razor blade. Tuck the yarn compeletely using a small screwdriver. - David Lyga
