Gas tank repair

[Fly boy]

The old 71 honda has a couple hole's in the tank. Is there any kit that works better then another, or google and buy the or second kit that I find? I'm just looking for a poor in, swirl around and let set if possible.

Thanks

holes inside the tank or outside? like as in rust or cancerous rust?

As is rust got to it before, and 1 repair kit couldn't do the job.
