I put this thread here because its more about fleet memebership than the ships. Also, this may be a sensitive subject depending on the answer so I will save you the time and tell you this is not my primary account.

Question is , if I find a tier 5 fleet yard and grind up the stuff and get a tier 5 ship what happens to it if I than leave the fleet? And the excess fleet credits? and any other fleet gear I grind up while there?

Also, when I join another fleet can I use the credits again in thier store?

Whatever you buy from the fleet store remains yours unless you discard it. All the fleet credits you earn are yours as well and can be used in another fleet?s store, if you decide to change the fleet.
