Tank Kreem opinion please

I've never used it to coat the inside of a rusty tank. Does it work or does it mess things up? I have several vintage bikes that needs this treatment but I need to know real world usage before I attempt this. (it's not cheap).

Also, has anyone heard of using pure battery acid to boil out the rust in a old tank? an old timer here told me to put pure battery acid in the tank for a few hours to eat up the rust flakes that don't get washed out.

thanks,

Dirtrack

Do NOT use acid, it will just make things worse. There are two coatings on the market, POUR and KREEM...from what I hear, avoid KREEM.
Not sure if it is in the achives or Vulcan Verses, but there is a proceedure using electicity to clean out the inside of a rusty tank. An sure someone will come along and post the link or porceedure.

Other than replacing the tank, this is your best option...

Thanks Knifemaker

Never heard of POR, VN750 and your comments helped me do the right thing without wasting money. My research showed that Kreem may not hold up to current fuel additives where POR can and is aircraft certified.

Here's a link for our members:

Here is the direct link for the POR-15 cycle tank repair kit. I used this kit on my tank and it did a very good job.

I've never seen a Kreem treatment that held up. Usually causes trouble right away.

I just read an article in Motorcycle Cruiser magazine. They poured WD40 into a tank with a handful of 3/8" nuts, after removing everything and blocking the holes. Shook the tank for about 15 minutes, then flushed it with gasoline(or brake cleaner). They say it will remove surface rust and that the tank can be put back into service after making sure the screen is clean. For more severe rust, they recommended coating the tank, but didn't endorse any brands.
I had a buddy take his to a friends radiator shop, and they did it for him. Not sure which coating they used though.

As far as the Por15 goes. I have many Hot Rodding friends that coat their vehicle frames with their product. Almost as good as powdercoating.

It looks like Por15 is the way to go.

My only question is can the Marine Clean and Metal Ready be poured down the drain or do I need to take special steps to dispose of it?
