Rusted tank. Any Ideas?

youngbiker
I want to do a liner but i'm not sure if there are any preparations i need to make before i do so. i've seen a lot of stuff online and on youtube and i was just wondering if i could get input from you guys.

I used this method and did not need a liner, plus, you won't have to deal with nuclear waste in your backyard - just good ole soap...

Apparently MEK works also.
So I have read anyways.

My assumption is the tank would re-rust without any coating. I am not sure how the acetone or mek will affect the tank for rusting.

Once you get the rust out, keep it as full as you can always, that will keep the rust away.

My strategy is to keep two five gallon gas cans stored for both emergency power (my generator) and the bike to keep it full.  If the gas starts to sit for more than two weeks, I dump it into one of my cars.  Just a suggestion.

Sterling makes a good coating , although it's a bit of a hassle to use , it does work well . -- I've also used RED-KOTE with good success . -- The best reason I can think of to coat the tank is the possibility of pinholes that will blister the paint first , and then start leaking on your leg . ( I speak from experience ) -- These tanks have been around a long time , and coating it is a good preventative measure . -- Gasoline running down your leg for an hour is not a good experience either . -- I just made it back to the house before she ran out . ---

Hey there otto! I can safely say I would not want gas on my leg! Bit of a fire hazard!

It was indeed a bit of a scary ride . ( I was just waiting for some idiot to throw a cigarette out the window ) -- Not to mention the chemical burns from the benzene .

Quoting "Re-run [via Honda CB750'S]" :

This brings up a very good point.  I've been looking at EBay and other sources for new/replacement tanks.  They're getting harder to find.  What would be a good replacement tank?  Getting one custom made would be prohibitive.  I'm not a real slave to fashion per se, but I like the look of the factory tank.

Any sources out there for NOS gas tanks?

You might be able to get one from david silver spares. I looked but didnt see one though you might email them.
otherwise, a bike boneyard is the best bet usually. I don't think honda makes them anymore.

True.  Boneyard finds may or may not be better than what one already has.  There's another option to find another tank, strip the paint, fix holes or line the tank, and then repaint it.  With my bike being one of those anniversary models, keeping it stock may increase its value. It's a quandry, isn't it...  It's possible that a person could spend 100-200 bux on a EBay auction, which in my case is 20-40% of the cost of the bike.

I'll keep looking around, and if I find something, I'll update.

The day is comming that we may need to start making our own tanks.
I havent De-Rusted my tanks yet but I have printed out the directions on how to do it. I plan to use motor oil to keep it from flash rusting on me. Used Motor Oil will work also. I plan to put it in after I get the moisture out wirh Brake cleaner. Roll the tank around so it coats the inside then dump out the excess since I dont want large amounts in the gas.

I like the electroplating process I've seen on other boards.  A nice layer of zinc on the inside of the tank sounds like a good thing. I've heard good things and bad about Kreem and the other processes.

If I go the electro route, I intend to get a very rusty tank from somewhere (maybe an old lawn mower?) and try it there.  I've got a 6amp battery charger which should do the job, and I'm sure I can find a nice bar of pure zinc somewhere for the donating metal.

After re-reading the procedure (Ken's Electrolysis Method) all it does is de-rust the tank.  It doesn't "plate" the inside like I was thinking.  So, the step after de-rusting is to treat the inside of the tank with POR-15 or some equivalent.

Although plating the inside would be cool, especially if it's zinc or some other non-gasoline-threatened material.
