I know this is a very controversial subject, but I personally would highly recommend water testing fuel tanks before closing them.
I'm certainly glad I did mine.
After leaving the tank sealant to cure for at least a week I decided I just had to fill them with water.
The left tank passed but the right tank failed. It was so much easier to fix with the baffle off.
My only tip would be to make sure that you properly dry the tank afterwards.
