    I used a junky battery tender, the tiny kind you get at autozone for $20 that's 6V or 12V. It has to connect to a battery to initiate a charge to, but you can vary the resistance of the water buy putting in more or less sodium carbonate (bicarbonate, I forget), and sanding the sacrificial anode so it's bare. Your mega charger would work, but you should research what the ideal method is, which I don't know.

    It took maybe 8 hours of being hooked up to the charger, with sanding of the sacrificial anode (which gets plated with the rust) every hour, or whenever the charger stopped charging becuase the resistance got too high.

    the whole process took a day. Boring and tedious, but incredibly satisfying at the end!

    I did a Honda C70 (shown) tank two honda hobbit tanks (with decent results, though the anode can only "see" about half the tank, and a Honda CB550 tank. The C70 tank is the best because the whole inside is concave. If the anode cant see the entire inner surface of the tank it takes longer, I think (but I may be wrong). Whatever is closest to the anode gets cleaned first.

    i tried to do that.

    i think my anode was the wrong metal - i tried using a threaded rod from home depot and it's probably some kind of zinc plated crap. anyway i got a lot of white/green foamy crud, kind of like you'd see at a nasty beach. no rust though.

    not sure how i want to proceed now. i bought the POR kit, so that money's spent. people rave about it generally, also. and i don't have phosphoric acid :cry

    edit: oh here's the skunk btw

    Please explain how it's way better than POR-15?

    For $47.50 shipped I can take care of the tank rust and never have to worry about it again.

    I'm familiar with all the different processes and methods several companies offer for this and the best one (and easiest) requiring the least amount of effort is hands down POR-15. I don't have a garage as I live in the city, your method would require me to purchase several things I don't currently own and have to look for to take care of this.

    Check out my write-up... super easy to take care of and to this day my Ninja tank is in superb shape (Ethanol and all).

    terrific write up, great photos. thanks for that.
    question: do you have to worry about the petcock holes (threaded bolt holes, main hole) with the sealant (final can)? someone mentioned that the sealant will dry in them. things like this are why i haven't gotten around to doing my tank yet :)

    Not at all, once you are done spinning the tank in all directions and coating the whole thing (letting the liquid go everywhere), you then have to pour the excess out and throw it away. Once you spin it enough and it has coated the tank perfectly, grab a box smaller than the tank ligned with a paper bag (that wont leak from the bottom) and place the tank on a corner (petcock hole facing down) to make sure even the smallest amount of excess drips out without smearing on your paint. Once that's done you are good because there wont be any excess to dry in any of the holes. I would then use the brush and go over any puddling in the petcock hole (if you're paranoid) and also go over the gas tank hole in case you missed that area (as it's typically curved).

    I'm a perfectionist with things, so after I thought I got all the liquid out, I held the tank upright where the petcock corner hole is (so stuff would puddle there) for 5 min or so, and then turned it and got even more stuff out from the petcock hole.

    It is super easy to do, remember the consistency is watery (I expected oily) so its easy to coat it everywhere inside and pour it out. Once you're done, just leave the tank alone for a few days and let it dry. I'm actually looking forward to doing this again this weekend.

    Can you clean my tank for me too :)

    J/K. Your write up was great. I actually read a few times. I just happen to have most of stuff to do the electrolytic method at my disposal. So I will give that a try. Hopefully my bench tester wont blow things up.

    I am actually doing this on a SV650 tank. This thing has two big holes, one for gas cap and other one for fuel pump. Got any idea what I can use to plug the holes?

    I also have two ideas in mind.
    1, half tank first, then flip it upside down for the other half.
    2, submerge the tank in a plastic container to charge the whole thing at once. I hope the two holes will line up so the anode will go thru.

    It's a learning experience hehe

    I'm familiar with the tank, I would just go to home depot, buy some sheetmetal or other material you can cut to the size of the fuel pump (drill holes etc) and plug up the fuel pump hole. The ways you suggested could work as well.

    the nice part is, i don't actually have any paint on this tank :rofl
    you've inspired me - maybe i'll actually tackle this over the weekend as well. it'd be nice to make some headway on that bike.

    Oh you're nuts. About 8PM tonight, before they plowed smith street, I went to drive my sister in law home. 10 min away mind you. The 2nd right turn, going 5MPH I turned the wheel and the car didn't turn. Brakes weren't even home. I smacked into a tree and broke my headlight housing and bent my bumper so now the wheel hits it when I turn right. Everyone is OK and the tree is fine but I promply turned back onto my block and parked. In fairness I didn't switch the 4WD on yet so that may have had something to do with it. I can't see going out on 2 wheels tonight.

    Friend from Poland is coming to NYC for couple of weeks in the summer and is looking for a BMW rental, 800 or 1200 GS. Can you recommend a rental place in NYC Metro area? I found Jupiter but their prices seems little high to my taste.

    The Harley dealer off of 17 in NJ sprung up a giant BMW sign. I know they rent harleys but it might be worth a phone call to see if they also rent BWM now.
