Heres what i did for my 200m tank. It was rusted through bad, it drained water faster than the garden hose could put out.

I started by shaking the tank with a bunch of screws, this broke down all the lose rust.
I then cleaned the out side and temporarily patched it with epoxy(quick steel) from walmart. <-- only needed if it leaks EVERYWHERE.
I filled it with white vinigar bought from the grocery store for $1.29 a gallon.
Let it sit for a few days, swishing it around every 12 hours or so.
Drained it washed it out with a little baking soda/water, rinsed it as best as i could. Coated it with acetone to clean it real good. - let it dry
This is the fun part. I took 2oz(1 tube) of Regular JBweld(NOT KWIK) I mixed it with 5teaspoons of acetone(safe according to jbweld), i poured half of it in the tank, 1 side at a time. I tilted the tank, letting the jbweld mix run to all the corners and cracks and holes. Then i poured the other to the otherside doing the same. This gave a nice coat to everything in the tank. You can see where it ran to by the nice shiny dark grey color. I let it set for 3 days, it takes longer to set up with acetone. Once dry, i repeated the process for a 2nd coat.

I then took some time and cleaned up the epoxy from the outside, smoothing it down, shaping it, making it look good. - then that was it, i got lazy lol

Been 4 months and no leaks. The JB weld looks good and is solid, no problems. - It can also be removed with heat(600 degrees+)

jb weld will hold up to gas but only for about 6 months if its in direct contact with the fuel, i jb welded my big red tank about 6 times before breaking down and buying a new tank, it would hold up but after about 6 months it would start blistering and leaking through... but i live in ny where the temp changes alot and I noticed the time of year affected how long it would hold

I'll keep the world updated on mine then, so far, so good. I live in Kansas, temps change about every day, lately been 40degree changes. Monday it was 101, Tuesday it was 60, wtf lol. Temps go as low as 0 in the winter, 100 sometimes 110 in the summer. If it hasn't started leaking, or blistering by then, I'll let you guys know, or as soon as it starts to leak.

They carry that stuff at Harbour Freight. I haven't tried it yet, but it seems to have good reviews.
