I was reading the thread with the Alvis tank and thought I will chuck my three hapence worth in.
I kept smelling petrol in the garage and eventualy realised it was a bit wet under the rear of the Morris. I drained the tank and removed it to find the cowboy before had painted over the corrosion with hamerite type paint. It had eventually failed - great!

I stripped off all the parts on the tank and found my heat gun, put it on the low setting and started to warm the tank to dry it out. When the tank was nicely warm all over I left the gun running for another half hour. I then cleaned all the paint and rust off.

I decided to put a soldered patch on the tank as this was possible to do in 1936. Whilst feeding the cats I looked at the tin and I had my patch. A pot of flux and some large bore solder came on handy. Being careful where the flux goes will determine how neat the job is and when the patch was on there still 2 small leaks. A pab of solder on the 2 small holes did the trick and a back up of Petseal made sure.

A lick of paint and back it went into the car. This was 2 months ago and no petrol under the car.

Good work - I too have used soft solder (applied with a big heavy copper soldering iron heated well away) to fill up these types of pinholes.

I doubt the Hammerite was actually used to fill up holes - its just no good at stopping corrosion in existing pits so it just carried on.

Its best to use a good zinc chromate promer with pleant of coats of enamel

Hammerite will seal small holes in a petrol tank but only for a while (selling the car). Anyway I used a heat gun to solder the patches and I used Red Oxide to prime it and then I gave it a coat of Rustoleum, it is the same solvent base as Hammerite but it seems to go on a lot easier and goes a lot further. I am not too worried about corrosion now as it does not go out in the wet.

I find a cup of tea is a must half way through painting the tank.

Hi Just a piece of usful info picked up years ago. Use Tipex correction fluid to stop solder running everywhere. Paint a barrier line where you want the solder to stop.
