Repairing pin holes in a tank

[Propellor]

Aye timbo,

Not the same I know, but after making some good chutney and leaving it to 'mature' in an aluminium jelly pan, said pan developed pin prick holes!  Aceatic acid! 

Quote from the dreaded Wicki P "Vinegar is a liquid consisting mainly of acetic acid (CH3COOH) and water. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria."

So, as you can see the added ingredient of 'petrol' may turn to vinegar in your tank like an opened unfinished bottle of Beaujolly! I know, that's anathama to many on this site! 

Anyway, as we were living 16miles from the nearest ironmongers and had a glut of apples to make into more chutney, the pan was filled with water and every water drop on the outside of the pan marked with a soft pencil. The pan was then dried off, given a wee dink with a ball pein hammer on the outside of each hole and then the holes were filled with 'JB weld'. The pan was then sat on the 'Carron' stove, like a 'Rayburn', and warmed for 24 hours. 32 years later we are still making jam, jelly, marmalade and chutney in it and the JB hasn't budged! 

Just don't leave the contents in the tank to corrode it, drink it or ride it dry! 

Good health to you all, Bill

Bill, do you have the molecular symbol fir JB weld? Failing that, the quantum number should do.

As for the bo jolly, I couldn't pissibly comint.

Oh, by the wAy.

CHEERS!

Aye, Propeller,

And this years Seville orange marmalade on toasted, buttered hot cross buns, with thick cocoa, afore sliding down 'sheet alley' after a day working on "Morini the Minx" is really tasty. 

Slainte!

hi  I put chemical metal  in a couple of pin holes in a gsx tank
its had petrol in it now for about 3 weeks so far so good no leaks

week 5 its leaking doh
so don't use chemical metal folks  tommy

[timbo]

Sorry to hear that you've sprung a leak Tommy  but thanks for letting us know.

[tommy]

I think I will try araldite next  tommy

[timbo]

Unfortuneatly I can't give positive feedback on the araldite, as I'm still waiting on Alison to primer the tank before any fuel goes in 

[timbo]

Ok, just thought id drag this old thread back up. I can confirm that araldite definitely isn't modern petrol proof. It lasted about three weeks before the petrol ate it and it lifted off in big flakes. So following Tommys previous post, we can now confirm that neither JB Weld or Araldite is a permenant petrol tank repair  So im going to explore the brazing or silver solder route, as I now have four leaky xbr tanks to fix
