Very good. They usually rust badly under the battery.
-
would anybody know what would fit in there i spayed some rust converter but now i can not get rid of the converter i tryed a die grander but it would not fit
-
turn the nut and it ought to either come off or twist the head and break the stuff loose.
if the nut comes off then knock it up from below and it ought to come loose.

go on powerblocktv.com there's a rust removal video clip there using soda ash, a battery charger, and a tank. i'm geting a big rubbermaid tub and doing it on my battery tray and seeing if that works.

That technique involves electrolysis, you can do it to any steel part you can fit in your "tank"..However, if you wire it backwards, you will end up making it worse. I used it on motorcycle gas tanks frequently. I used muriatic acid instead of soda ash, but any strong acid or base will work..You'll need another piece of metal in the tank where you connect your other terminal for the rust to move to. I don't remember how I wired mine, its been about 4 years, and the battery charger I used had no indicators of polarity..I used a rusty bolt and a clean bolt to test it, and I wired it right the first time..I did test the polarity before dipping a fuel tank, but I forget what it came out to be. IMO, for items you can sandblast, I'd sandblast em instead of removing the rust via electrolysis..its faster and safer..the inside of motorcycle gas tanks are rather difficult to sandblast...

you hook the neg charge to the rusty part, the pos to the other that you're sticking into the tank.
