Coke didn't do it

Ime it falls into the 'life's too short' category. Just pour a bottle
of POR-15 Metal Ready (or whatever they call it these days in), let it
do it's stuff, drain it back into the bottle ready for next time &
bob's yer uncle. The bare metal will be etched, the rust sorted, & the
whole lot coated with zinc phospate, all with virtually zero effort.

 

I'd still seal it after, but as it's TOG, this could be a 'tart up for
sale' job rather than make it last for many years.

 

<Looks guilty>

It's a really, really good 400 Four tank. Excellent condition and it's
very solid - there's just a lot of surface rust inside, that's all.

 

I'd still give the Metal Ready a go. You'll be able to reuse most of it
on other rusty stuff so it's not like you'd have to write off the full
cost against that one tank.

 

This.

 

A quick descaling *IF* you can get the pebbles thrown into the tank back out
again and you can't descale it with stones/pebbles, get it to a place with a
steam cleaner (not a jet washer, nowhere near serious enough) and let them
have it for 10 minutes. There won't be any loose rust after a damned good
blast with a steam cleaner.

Let it dry thoroughly and then throw in the contents of a couple of bottles
of Kurust and slosh it all around. Despite what some people say about
Kurust, it actually does what it's supposed to do.

Then, when the tank is once again completely dry, Flowliner the fucker.

 

Should've gone to "Use A Paintshaker"

 

<jogs Beav's memory>

Flowliner's been pulled, remember? Ethanol kills it. Well unless
they've bought out a new one in the last couple of months.

 

All depends on how rough the rust in the tank is.

If the tank was that bad I'd simply buy a replacement from a breakers.

Phosporic acid?

 

Phosphoric Acid is the ingredient in Coke

We used it as a bath for our molds that
molten aluminum was poured thru

 

Um, you're responding to the breaker.

 

Black treacle I tell you.
It will cost you £1 and 3 weeks to see if it works

 

Whoosh

But hardly a high enough concentration to be useful

 

Yep. I've seen it work - and no, I was sceptical before the proof was
(literally) shoved under my snout.

Heh. As it's TOG, he could just as well use one of those XS tanks he's
wedged out with.

 

No, I didn't know that.

No idea, but I'll get my investigating feet on and check.

 

As promised and it looks like you're a bit wide of the mark.

Quote from their website today.

"Most fuel tank coatings have and will eventually fail due to the recent
introduction of ethanol, FLOWLINER ARMOUR COAT is resistant to alcohol
products such as ethanol.

Description:
FLOWLINER ARMOUR COAT is a two pack solvent free epoxy fuel tank coating,
which when cured will form an extra strong lining inside the fuel tank, this
650 gram kit will treat most tanks up to a 25 litre tank. You may use less
quantity but the mix ratio should be 100 to 25 of hardener measured by
weight".

It's the "2 pack epoxy" mention that gets my vote. That stuff is generally
fooking god shit.

Not really, they have indeed brought out a new 'ethanol proof' one.
