Kreeme will work fine as long as you treat the whole area. Any rusting or non etched surface it will not stickk. If you have holes on the bottom inside, jb weld works fine to fill them. But if it is on the outside, then you need a better fix. Jb weld weakens over time anything that hits it, it will fall out. Underneath really never gets hit. To stop pooling on any of those products, you have to start in thin layers. I can do 4 gastanks with one Kreeme kit. I have never tried the red suff mentioned here. There is also a product out there called Por-15. I have not tried this but if I need to redo my gastanks, I will go this way next time. Anything that etches the metal, (muriatic acid or any other acid you use) should be treated. Honda tanks came treated originally. The acids use with these products takes that coating off. If you have very little rust, I recommend just a simple flush, with MEK, acetone and leaving it alone. Basically pulling articals out of gas tank. Gas does not cause rust, Water and air do.
