I was recently surprised when our aniline sofa had some stains disappear over time - I'd never heard about that. Still, protecting would be a better idea.

1. Is this Leather Solution something that once you start with it you have to continue? I can see myself 10 years from now wondering whether the cost is really worth it.

2. Also, does it turn this nice, breathable leather into an expensive protected leather? I really dislike hot, non-breathable "waterproof" leather shoes.
