Need to repair the tank on the monza. Can only find one small hole near the back but pretty sure it will have gone pretty rotten on the top.
My normal way is give it a good wirebrushing any holes i can find fill with epoxy putty. Then fibreglass it. Anyone with any other ideas.
I would just get a one from the scrapyard but chances are they will be pretty poor as well.

Plug filler neck.
Rotate so the hole is at the top of the tank.
Fill with water to within 1-2" of hole.
Burn off the remaining fumes in the 1-2" of 'open' tank (should make a satisfying 'pop' as opposed to the life-threatening boom which would occur if there was no water in the tank).
Weld plate over hole.

I did my Manta tank. It had holes where the straps holding it to the body trapped water.
I removed it, drained it, flushed it and left it outside to air on a lovely warm day for a few hours then welded a patch in place.
I did try the quick fix repairs, they just didn't work. There's really no substitute for doing it right.

Ive welded them before using penski`s method but that has just been when I have holed the tank. When the whole tank starts to rot Ive found its difficult to repair by welding. As far as I know most companies that repair tanks basically just dip then in fibreglass.
Of course I could stop being a cheapskate and try and by a new one but I begrudge paying that much on a £500 car ;D

Heard a story once from a guy who'd done all the stuff listed to a tank before welding it up, the resulting bang when he started put him on his back and blew his garage window out when it ruptured. He did some research and found you should fill it with an inert  gas first such as argon. I'm far from an expert and my head is too full of curse word to remember half the stuff I hear, but it might be worth checking out unless somebody knows better? Just a thought  |

Many years ago, a local garage where I lived at the time had a welder working there whose nickname was "Teflon" (no prizes for guesssing why).
He thought he'd be OK by just draining the tank before welding a patch on it............
He ended up in Chepstow burns unit (via ambulance, not from the explosion!) and nearly bagged himself a Darwin Award.
