I'm looking for help on repairing a few rust holes in a older metal gas tank. I was thinking of using JB Weld, but wondered if anyone had tried this, and if so did it work? I also want to use the "Creme" coating kit on it after I repair it to seal off the entire inside. Will the Creme products eat at the JB Weld repair??? Any help would be greatly apreciated!!!
Thanks, Rude Dog

Update:
I sanded the effected area's real good. Then I (get this) used nails heads to bridge the gaps. I cut off all but about a fat 16th of the nail and stuck them into the rusted out spots. Then I applied the JB weld over the area's. So far so good it's holding. I currently have the tank full of the first part of the kit (A) and I see no leaks at the repaired area. Once I dump out the etcher solution I then have to use part B (neutralizer) and then part C the coating. If it gets through the part A okay I think it's going to work.

P.S. This is a fix-it till I can find another tank. So.. If anyone has or knows where I can get a used Honda SL125 tank let me know.

2nd update:
Checked on tank this AM and found that it had sprung a small leak. The leak was only a pin-hole, but it allowed about a 6th of the etcher solution to leak out. I dumped the remaining solution, rinsed and added the neutralizer. Dumped it out and added the coating (Part C) all looks okay. Re-installed the fuel petcock. Hopefully it will cure by mid-day tommorrow so I can add gas and see if it will fire.
Thanks for all of the reply's!!!

Final update:
Finished with part C (coating), let cure for a couple days and then filled tank with gas. All looks good so far with the tank and fuel system IE: no leaks!!!

Sorry that I didn't see this post earlier. My buddy works on old ATCs with metal gas tanks and he has used Creme several times with great success.

Creem is good for awhile but after a few years it will flake off and get in your filter and carb.Had this happen on some old Harleys.

I have repaired old jeep gas tanks with fiberglass and had no problems. I covered bad area with a layer of cloth and 2 coats of resin. Also doubled the value of a ford car when I sodered a dime to the gas tank. I used an electric soder gun so there would be no flame and it does't get to hot.

Take it to a local radiator shop. I have seen them do miracles on car gas tanks. An ATV tank should be a breeze to them. Check around your area, see which radiator shop also does gas tank work. We have a real good one here in Ocala, FL.

Never used JB weld butr at auto places they have and epoxy that is fuel resistant but since you plan on Stripping the inside of the tank and sealing it I don't see why it would matter.

If all else fails. Wash tank out real well with soapy water and put some water in tank and use a torch to braze the hole shut. I had to do it on a few tanks. just make sure you have the tank opened and noot sealed. It works very well and last for a long time.

Never thought of exhaust gas that's a good Idea I will have to keep that in mind.

I have used jbweld lots of times on gas tanks. just make sure to clean the spot real good with sandpaper and it works great! I don't know about the cream.

Yep brazing is the way to go. Or if you can afford it go to a welding shop and have them TIG weld it. Not as much heat has to be put in as brazing and it wont distort as much. Tig welding if done properly should give you a tank that is as reliable as new. If you don't like the water idea(which is good by the way) you can fill it with an inert gas, argon, CO2, even run a hose into the tank from the exhaust of an engine. I've had to do that on the job a few times with vehicle gas tanks. And yes leave the cap off(which is also good,otherwise if it does blow you'll end up with a split tank or one that holds a little more fuel, misshapen but it'll hold more, trust me I know from personal experiance, what's that you say huh I couldn't hear you) Oh yea if you haven't figured out by now I'm a welder.

PS JB weld is not a professional way to repair steel, but then I may be biased as I am a professional.(20+ yrs,x-ray,aluminium,stainless steel,mild steel,pipe,you name it)
