Nuts in tank : )

[loki7714]

Think if i use large nuts to derust my tank and put a large magnet on a stick i could get them (and the rust) all out? Looking at this as viable option for de-rusting tank now that my filters in.

[Tang]

bwahaha that'd be funny and if it'd work that'd be crazY!

[loki7714]

Lol yeah a friend told me he did it on an atv tank with peagravel or rocks or something and he said it worked fine so... (Also the wiki lists peagravel but how the hell you'd get that out of a gs500 tank don't ask me 

[ohgood]

pecan shells are good at deburring metal...

walnut shells are better ...

the problem is do you really want to put your tank in a cement mixer for 2-3 days with nuts in it ?

use acid instead, it's fast, easy, and done without destroying the tank, your cement mixer, or your nuts !

[loki7714]

Lmao meant metal nuts and thought i'd just shake it up a lot lol (plus force lil bro to help lol). Acid does seem like a good alternative though, reccomendations/tips on acid?

[Tang]

man i dunno but i'm in the same boat as u i need to get rust outta my tank too but don't feel like forking over cash haha

as soon as u find a solution let me know lol

[loki7714]

lol heard about one guy who put nuts, gravel, watever in his tank wrapped it in blankets and threw it in the drier.

dunno if u checked this out yet

[loki7714]

Cool. Think i'll be fine with acid and fuel filter though.

[Tang]

word tell me how that goes for u

[loki7714]

K think i'm gonna try the acid that doesn't eat rust as much as change it into some sort of iron... As soon as i scrounge up the money

Don't use nuts,it's hard getting them all out even with magnet,I should know

And for the love of God, never use chain!

[loki7714]

Chain sounds like a good idea... Why not?

[The Buddha]

In a GS tank neither chain not nuts can reliably get rust out from the most important location of all ... where 99% of the leaks occour, and where rust is installed at the factory ... that's right, they install it at the factory. What is worse, and I dont have proof of this cos I never did try it, even electrolysis will not get rust out of there. The crap pocket.

The best thing about acid etching is that, it will prolly attack the crap pocket a lot harder than it will attack everywhere else, you have trouble getting things out of there ... so acid gets in and eats it good. Chasing that acid with hot water and baking soda should get it killed off.
Cool.

I did this on my tank before coating with por15 on my first bike. It was a trick I learned from my stepfather and he swore by it. I only out about 1000 miles on the bike before I sold it but it seemed to hold up well for that time!  Trick to remember is you are going to need to do it for a LONG time, and when you think you've got it all then your halfway done! Also use an assortment of different size nuts and bolts but make sure they ALL get out when done!

I sandblast tanks here using special equipment.

Here's the result:



This bike had over 2 gallons of water in the tank.

Sandblasting has the added benefit of providing a "tooth" for the tank coating to adhere to.  The metal as-fabricated has a cold finish, which is not conducive to mechanical bonding of the tank coating.

[loki7714]

Cool looks like a lot of rust left though... Coating should deal with that though.

[GeeP]

That's just the discoloration and pitting left behind by the rust.  The rust is gone.
