I searched.
Seems like nobody mentioned this Rust Bandit solution yet - http://www.evaporust.com/rustbandit.html (http://www.evaporust.com/rustbandit.html). Etch rust with Evapo-Rust http://www.evaporust.com/evaporust.html (http://www.evaporust.com/evaporust.html) and apply Rust Bandit. Seems easier (and less harzardous!) than acid+ POR or Kreem stuff.
It is cheap too. 1Gal of Evapo-Rust is $21. Same quantity of Rust Bandit is $18.
Too good to be true?
Any thoughts?
Yeah I've used several Gallons of Evapo rust. :thumb: I usually pick it up at Auto Zone but it is $8.00 a Quart there.A full Quart will usually Derust a Tank if you keep sloshing it Around for a few days.Ill have to try some of that Rust Banditand see how it works.Thanks for the Tip. :thumb:
Hmm I've been reading.Something tells me it wouldn't stand up to gas Very long. :icon_confused: Also it may be something that you may not want going thru your Carbs Either. :icon_confused: :icon_confused:
Here's email I just got from their Customer Serivice:
"Thank you for your inquiry. Yes, Rust Bandit will work for your gas tank. You will want to dilute it 1:4 to 1:7 with water, coat the inside and pour out and allow the tank to dry completely. Once you fill your gas tank with gasoline, the protection is no longer actually needed as the gasoline and vapors keep oxygen/moisture from the tank (in theory).

So after some more reading it appears it will work, but it does not look like a long term alternative to Kreem/POR. Even though gas is not reacting with Rust Bandit, any amount of water in the gas will rinse the protection off: "Rust Bandit is extremely water soluble, and does not need much rinsing to remove it from an object. In general, a 5 second rinse with tap water above 60 degrees Fahrenheit (16 degrees Celsius) is all that is required."
If you plan on doing tank flush at the end of every season (which is not a bad idea to get rid of gunk, condensated water, etc.) that may work for you.
Still, EvapoRust looks less hazardous to etch the tank then acid as the first step.
From the website:
EVAPO-RUST is non-corrosive to steel and does not harm brass, copper, aluminum, gold, lead, titanium, steel, cast iron, chrome, solder points, vinyl, plastic, rubber, silicone, glass, cork, or wood
Since its non-corrosive to rubber and plastic, would it be safe to keep the petcock connected to the tank when I use evapo-rust
Evapo-rust's directions for a motorcycle tank:
You can use Evapo-Rust to remove the rust from a gas tank in one of two ways described below, depending on if your tank is still attached or has been removed:
1) Completely fill the tank with Evapo-Rust and allow to sit for 2 – 4 hours. Drain completely and rinse well with water. Air dry and fill with gasoline immediately to eliminate flash rust.
2) Pour in 1 gallon of Evapo-Rust and rotate gas tank every hour until the rust has been removed. Drain completely and rinse well with water. Air dry and fill with gasoline immediately to eliminate flash rust.
No mention of removing the petcock
