What is the overall length?

NOT CONTINUOUS.. BREAKS EVERY 3-5’.

how well would this work on sealing the door on a gun safe?

I've never used it on a gun safe but I have used it on the door of a Weber Smoky Mountain and it worked fine. You may have to thin it out some in order for it to work in other applications.

Will this work on a green mountain daniel boone?

I bet it will if it has a lip close to the same width as the seal. Clean it with alcohol and use the food grade hi heat silicon first.

What exactly is it made of? Is it soft and cushiony?

It is made of nomex. Yes it is soft so it forms a seal.
