Default Tank Repair / seal

I've just been out to give my excellent condition 1986 GPZ1000RX a run and
noticed a melted side panel. Seems the tank has been leaking slightly over
the winter. I scratched away at where the tank paint was blisters and a 1mm
hole appeared. It is just outside of the under tank weld at the back of the
tank side. Is it a hopeless case and should I buy another or do you have any
suggestions about repair? I expect even if I but another second hand one
tanks of this age might all be subject to internal corrosion.

Thanks

Jon

All these magic gunks, sealants and unguents are really only stop-gaps
if a tank is seriously corroded. You have a choice - find another tank,
and as you say, it may be in the same condition, or hand the tank to a
professional repairer to have the corroded bits cut away and a new
section welded in, refinished and made good.

Which won't be cheap, of course.

You might be lucky and it's just one hole, in which case Plastic Padding
Chemical Metal or Leak-Fix (same stuff I think) will do the job if applied
to clean dry metal. If it is the whole tank going, then it obviously won't,
but it might help to keep you going until you find a better tank or a good
repairer.

Worth a try IMHO...

Alternatively, having a tank welded by an unprofessional person is
supposedly one of the cheapest ways known to NASA to launch oneself
into orbit.

Firstly clean out the inside of the tank as best you can and try to
remove all the loose rust (a handful of nuts and bolts, and a good
shake about works reasonably). Next get a hose and fill the tank with
CO from the exhaust of another bike or car.............then sand off
the paint from the areas that look dodgy.

After you have it the paint removed you will probably have quite a few
pin holes, in the bottom of the tank. However these can be easily
repaired with a fibreglass kit available from Halfords. After
fibreglass is fully hardened, you can finish it off with body filler,
and shape to blend in with rest of tank. Finally use something like
"Petseal" inside the tank, and other than painting the jobs done.

This is all a bit of a hassle to do, but is well worth it if you cant
get a good s/h tank, or dont want to pay someone around £200 for a pro
repair job.

Nah. You just get big purply blue flame and a bang that makes the shed
walls rattle, immediately follwed by such awful shakes that one could
weld one's own signature in under a second.

Aparently.

Flush it out well and fill it with water. Works fine.

This stuff works well in areas like the back corners of the tank, or
along a seam as you can pack it down against something rigid. It
doesn't work so well if it's just on a hole midway along a sidewall or
something as there's nothing for it to grip against. But it's worth
trying. The POR and Petseal type of fluids that you slosh inside the
tank don't work that well if the tank is already holed - they're more
for fixing light internal corrosion where flakes of rust are floating
about in the petrol and then gumming up the taps or carbs.

*I* know that. Actually the recommended way (at least to weld car
tanks) is to fill them up with water before you weld them...

I've never quite understood this. Big bangs n'all you avoid, I can see,
but how do you actually fill it up?

After all, the reason you want to fix it is that the thing leaks...

Posted yesterday advising the OP how to do an effective home repair on
his tank. I dont know whether its that helpful for someone who has to
pay others to work on his bikes, to offer opinions about something they
clearly are not familiar with?

Once it's full just bung it securely. If you're lucky, the original
petrol cap will seal properly with just a touch of gunge over the
breather pinhole, then orientate it for working on, with the leaky seam
uppermost.

If you're not too worried about appearance and just want a leakfree tank
until you find a proper replacement, you can employ the fibreglass art.
It works well if properly prepared.

The usual way used to be to clean back to bare metal round the hole,
fill the tank with sand, make a slight indent round the hole using a
ball-peine hammer as a punch, and filling the depression with solder.

Even soldering a tank full of fumes could (theoretically) do the NASA bit.

Hang the tank on the end of the car exhaust - the exhaust poking through
the filler hole, if it'll fit. If not, use a hosepipe. Run for 10-15
minutes. The gases purge the tank of all fumes.

Heh. A bloke my brother knows managed to set the tank lines alight on a
Reliant while he was welding the chassis. The car caught fire and then
basically melted into his inspection pit.... and then _set_!

Solder or brazing in fact, should be fine if the rest of the metal is
good.
As GC suggested Glass fibre, with a good overlap past the hole, works
but brazing is so easy why compromise.

That unforges me of a time long ago when one of my fiends was an
apprentice, or a recently time-served fitter at Plessey's, and one of
his mates asked him if he could use his old man's pit.

Ken said OK, but they wouldn't be there over the weekend, but the key
was always left under that brick...

He got back and a delighted neighbour described the scene: bod drives up
to garage and opens the gates, opens the garage doors, and drives in -
forwards - in a Reliant...
