Preservatives when racking and bottling?

[John Doe]

I'm still pretty new to this, but so far everything I've made has come out great! Wondering if I should be adding something like k-meta as a preservative for long term storage.
I'm not looking to stabilize and back sweeten as I like to just let things ferment out over time.
Also wonder the same thing with Apples wines I make.

K-Meta as an antioxidant is highly recommended for any long term storage.
