1st off you should store a steel bike indoors. And then apply this to the inside:

ok firstly, it IS stored indoors. I live in an apartment on the 11th storey. Several miles away from the sea(about 30mins walk). Is that bad?
Secondly, I've heard of this frame saver product before, but how does applying it on the INSIDE of the frame help prevent rust on the outside of the frame?
