Petseal etc.

The standard Moto Guzzi fuel leak from behind the badges - this time it's
only slight so what are the tank sealers of the moment?

 

POR15 worked well for me on the ancient Puch moped tank used on the
Forgotten Error, but it wasn't actually leaking, just very, very rusty
and flaky internally.

Yep, POR15 is good stuff.
I repaired one sieve^Wtank with it and it held nicely.
Nowadays I give a precautionary dose to any tank that looks even a tad
rusty on the inside.
It is important to get the worst of the rust out first and make sure
it is completly dry. I use about a pintmug of small gravel and shake
until my arms hurt, others suggest nuts&bolts. Always remove all
petcocks, drains, etc first.

 

This stuff?

Is it just the single tin?

 

Indeed.
Thats the one, same supplier as I use.

 

As has been mentioned before, make sure the tank is as clean inside as
humanly possble. I've always favoured the cheap coke or phosphoric acid
method over filling the tank with nuts and bolts or gravel.

 

And try getting all the sand or stones out if there's an anti-splash filler
neck which sits deeper into the tank further than the top of it.

 

There is that to think about too, but it was crn who suggested it, so
only those who deserve the pain would have listened to him

 

Never had a problem - the stones shake out easily.
Then it gets a washout first with petrol then with thinner.

 

I got a kit from Frosts including 'Marine Clean' and 'Metal Ready Rust
remover' for preparation.

Their Motorcycle kit comes with an 8 oz tin of the POR15 sealer, which
they also list separately on their web site for just £9.50 - except that
it is currently showing as out of stock.

Indeed and it would cause considerable pain too.

 

What utter bollocks. If you can tell me how to make stones (every last one
of them) successfully jump up and out of a fucking tank with an anti-splash
filler, I'll arrange for someone to come and give you a fucking blow job.

 

This is just great - he must be up to three or four a week by now.
Keep it up, crn!

 

Have you stopped to consider what it is that beav does for a living?

 

Define "eventually". Is your eventually when the bottom of the tank fall
off through rust?

I'm sure you do and I'm equally sure it works perfectly too.

Well why would you, you've got some free stones.

 

Maybe I should just post him some pictures of the tanks I've descaled,
treated, sealed and painted, none of which have been a problem since they
were done? Actually, I don't think I'll bother.

I use a product called "Flowliner" for the final sealing and although it's a
fucking **** of a job to get it everywhere (time really and arm ache rather
than ball ache) once it's in, it's in forever.

It's a 2 pack product which is both ratio dependent (product to catalyst)
and *very* temperature dependent.

The "left overs" in the mixing cup sets like granite.

 

Speaking of free stones gives me an idea, because here's a great
example of turning adversity to advantage. Loz could have a whole new
methodology available to him: he could drink the coke, then piss it out
into the tank. Hey presto, instant rust-abrading mixture - the
phosphoric acid in the coke and a couple of kidney stones into the
bargain.

It could cut down the amount of shaking required considerably.

No problem, both methods work. Personal choice innit.
