The perennial problem - tank lining

<< < (2/3) > >>

Laverda Dave:
I received notification yesterday from Andy at Motorcycle Dent Removal that my tank has now been internally plated.
He is posting it back next Tuesday (should have been today but I'm away until Friday so unable to accept it at home).
He has sent photos.
If you can wait until next week when I am back home I will add the photos here of what I started with, a very flakey rusty tank even DEOX-C wouldn't touch, to Andy's first pass with the cleaner he uses, second pass and prep for plating and the plating itself.
Be warned though, it isn't cheap but it does have a lifetime guarantee and unlike a liner it won't flake off.

Grewth:
Thanks for all the replies  !
Yeah,  I'm not a great fan of tank liners, but I really don't think that bare steel is a viable option anymore.
Ethanol absorbs water on contact, so as soon as it's exposed to humidity in the air, there's a corrosion risk.
Now electroplating the inside of the tank is something I hadn't really considered.
Basically you just need to turn the inside of your tank into a little electroplating vat.
I'm sure there are complications to be overcome , but the basic idea is sound.

Laverda Dave:
Here's the process in photos undertaken by motorcycle dent removal.
I began with a really badly corroded and flaky tank.
Deox-C wouldn't touch it
Sent to MDR who used a cleaner to remove the worst of the rust in the first pass.
Treatment a second time and the paint had to be removed from the outside of the tank as they thought the seam had corroded and the only way to check properly was to strip the paint. The bare tank was given a coat of primer on the outside.
Tank then prepped for electroplating with I understand Nickel
Lifetime guarantee provided against corrosion.
It was expensive to do but at least it's fixed for good and it's guaranteed and I won't have blocked carbs that would be a pia to continually remove and strip to remove rust or flakes of disintegrated liner!

Bryanj:
Might one ask how expensive?

Laverda Dave:
Just under £1k but that was without the paint strip and primer.
Sounds very expensive but normally the exterior paint isn't affected. The paint on my tank has to be stripped to find a potential leak.
How much is a liner (I know it's a lot, lot cheaper) and all the prep time and still not knowing if all the rust has been removed prior to pouring the liner and even then not knowing if the liner has covered the interior fully. It is hasn't it will lift. Then there's the issues we now hear about of some chemical liners failing and flakes going into the fuel and blocking the carbs etc with the result endless strips and still being left with a failed liner.
Plating is (to my mind) the best one stop fix solution and it has the guarantee so if it does fail it will be done again foc.
