Leaking Tank Fix

Hey I have a 8x4x4 stainless steel tank. It was tig welded. There are 3 spots that are pin hole sized that's leaking on the bottom seam. Tried using silicone lining the entire inside seams then let it cure for 2 days and filled it up with the same leaks. Really don't want to tear everything down to take it to a guy that can re weld it. Any suggestions on a "Fix" to stop the leak besides the silicone? Thanks!

    McMaster Carr.com has this, I used it to seal up 5500 gallon tanks. Works great, but you may need to rough the surface. Its 2 part putty that you mix by hand, like the stuff you find at walmart. One stick should be more than all you need.

    Jb weld water weld.. Used it in an old pump sprayer that had a pin hole. It holds under pressure and does not leak.

    There is a product called splash zone it will work in the water and it is best to mix part A & B in a bucket of water. I work on ships and this is what we use for emergency repairs all the time.
