Evapo-rust for the inside of your tank?

Could I use this in my tank? Or would that lead to unwanted explosions...

 

I'm going to use it in mine - feel free to check up in my seca thread in a bit as I'll post my results there.

 

cool

 

I'm also thinking of getting some gravel - so then i can fill it completely to the top - and the liquid will completely touch every part of the tank. at least thats what i thought up before going to bed last night, haha

 

I'm going to fill it with this: http://www.lowes.com/pd_92130-76450-GP0 ... facetInfo=

 

I'm going to do a friend's gs1000 tank. I saw the procedure on basscliff's GS page, he did a tank and documented the process using evapo-rust. I have a gallon of it, just waiting for the inspiration.

He uses 1 inch roofing nails for physical agitation of the rust inside. Seems like a plan to me.

 

it's a lot easier to get something magnetic out of your tank with a magnet than try to shake the last few rocks out and round rocks won't get in the corners where the rust is

 

oops...... lol.

It may be a little harder, but ittl be alright... well.... it's going to have to be, lol

 

I figure a shop vac taped to a 3/4" vinyl hose through the fuel sender hole will be able to clean it out no problem.

 

i took a shotgun shell apart and used the buckshots....im backwoods though. Winchester Super X (steel)

 

An old chain does the trick

 

Some BBs have always worked for me. They are cheap and easy to remove.

 

So for the first day i turned it over a few times , but was pretty sure it wasant going to reach the entire backbone unless i bought 2 more gallons of evaporust. Soooooooo, i put the entire bag (.5 cu ft = 3.74 gallons) of pea-gravel into the tank

Now with the displacement of the stone, it easily covers half the tank on every radius - so i'll give it a day on top, a day on bottom, a day on each side, and a day on each end, and then i'll dump the stone and drain the evaporust, and see where we're at then. Heck, might even give it two days per turn, why not? have all the time in the world.

 

Well, mine didn't work out so good. Turns out the bottom of the tank has many holes, all conveniently hiding under the paint. The rust has eaten through.

After I saw the leak spots, I took the wire-wheel to it, and found many problem areas, like 8" x .5" section, plus other smaller open spots.

ugh.

 

Damn, that sucks man.

Mines sitting in the second to last position, it's on the nose now, and next will be leaving it directly upside down.

 

I bought one litre of that stuff because it is too expensive for the moment and also because I wanted to experiment with small parts and diluted product.

I put a big washer to soak in 50-50% Evapo-rust with water this morning, I'll let you know tomorrow how effective it was.

 

FWIW, stuff was working, but my issues became much more involved than just de-rusting, moving more into the -reconstruction- phase.

Speaking of, has anyone on here worked with these:

I've been looking for something as a replacement, and this may fit the bill, as GS tanks are hard to find.

 

hmm, i wouldnt dilute it if it were me.... its worth it.

 

Well, I diluted a very small amount of it (not even 50 ml).

 

Diluted Evapo-rust 50-50% with water performed great over night on surface rust. There is still some deeper rust left on one side of the big washer I have soaking, so I'll let it in there for another day to see if that rust will all disapear by itself or if it will need 100% pure product.
*************************************
Edit: Deep rust disapeared after 48 hours. I'll have to try it again with similarly rusted parts, one in pure product and the other one in diluted product to be able to compare, but it seems that diluted product is OK if you're not in hurry.

 

I use Evapo-Rust exclusively on all parts that need rust removal Its great stuff. Also the BEST tank lining kit comes from Caswell Industries. I used it to line the tank from my 73 Suzuki GT750K a few years ago.
