Thoughts on preventing newly de-rusted tank from corrosion.

After the fantastic response to me asking about removing stubborn carb drain screws....

What's everyones favourite treatment for the inside of fuel tanks after de-rusting (assuming the tank is not going to be filled with fuel for a long time). Anyone know how Honda did this ? .. I just looked at the inside of a 52 year old NOS tank that was missing it's original tape over the filler hole but absolutely no signs of corrosion whatsoever. I am having this tank painted another colour and amazed how thin the original Honda paint is, with no obvious evidence of any form of primer, yet the paint finish is blemish free (original finish was  metallic not candy paint)

many years ago I bought a new old stock cb350k tank from David Silvers stand at the NEC (1986) and it had a very thin film of oil inside.

SteveW:
2 stroke oil?

Nurse Julie:
Anything oil based... We store tanks full of diesel for long term storage or swill the diesel around the tank and empty if you prefer. It is the film of oil that gives the protection.

Rob62:
A bit of 2 stroke premix sloshed about will do the job.... rinse out before use and shouldn’t cause any smoke. Just out of interest, i recently acquired a rd350ypvs which had a bit of rust inside the tank.... i have previously used electrolyte and a battery charger to de-rust tanks but its a bit of a faff although it works well. This time i decided to try some of that evaporust stuff that sounds too good to be true.. its £30 for 5 litres but can be reused..just pour it in and wait...its not acidic or caustic so doesn’t attack paint plastic or aluminium or the steel itself (acid does). All it does is break the chemical bond between iron and oxygen thus destroying the rust, it isn’t strong enough to break the bond between iron and carbon so doesn’t damage the steel either.... but best of all it actually works brilliantly! You can also derust any other ferrous object, old nuts and bolts, tools, brackets...anything. Just drop them into a container of the stuff for a few hours... then pour back into the bottle to be reused again... magic.
