There is an aircraft tank sealant that is not expensive and is obvioulsly very safe to use. It seals up pin holes but more important it just seals in all the rust flakes and particales. If I can find a link to it I will post a link. I have used it many times, mostly just to get rid of all the rust junk. Larry
Sounds like an idea, which one is a liquid so it can be poured in and rooled around to seal and pour out?
