I was about to reload my RZ67 120 back today and I noticed a loose bit of lightseal foam on the clam shell back. I tried to push it back into place but it proceeded to disintergrate. I guess now is a good time to check all the other seals. I have some light seal foam left over from doing my OM1, so I was going to have a go at doing it myself. Does anyone have any instructions on how it is done on the RZ?
