Fuel tank trouble
« Started on: 22-Jun-20, 16:40 »
ello everyone,

i’ve been working on getting the rust out of my tank over the last month with little success. Been using a variety of tips from the forum and elsewhere to no avail. To throw a spanner in the works i’ve just ruptured my Achilles and am out for 12weeks. So I’m pleading for help here really, if you have the skills and knowledge please lend a hand. One of the only things helping me in iso was working on the bike but now i can’t even do that.

Willing to pay for materials and buy beers, travel to you with tank, whatever it takes. I just want the bike good to go when i get out of this damn moonboot.

I get the rust out no wokkaz but the flash rusting is killing me and i’ve tried sealing it with a special paint as well.

Located in inner northern suburbs of Melbourne but like i said i can hobble to the car and drive to you.
Cheers in advance legends,
James

I spotted your post on the US forum before I saw you have a thread here and I've left you a reply in more detail there.

You need to neutralise the acid and then dry the tank with metho followed by WD spray.

Mins Man on the forum (Harry) lives in Melbourne and has done a few of his own tanks. Not sure if he is willing to do anybody else’s tank but it may be worth asking him.

You mentioned trying to seal it with a special paint , , what was that ??   I'm just curious.

I have a tank I'm going to clean out , I'm not sure what is in it but there is a huge amount of it.  Fortunately so far no signs of leaks.

Thanks again @CX PHREAK
@Seagrass i’ll message Harry and see what the go is there 👍🏽
@Onetrack i believe it’s a euro, yes where are you located? (Scratch that I’ve just seen, bummer)
And @308GTSi i saw a youtube video that used a similar method using a metal cover paint that inhibits rust but i think my issue was not neutralising the acid well enough before coating and drying. I used sca’s metal cover epoxy enamel paint...

Acetone should strip that paint out.

 In my opinion the only tank liner worth a cracker is Por 15.

My 500C tank was done 12 years ago and is still good.

 I recently did another tank with the remainder so it has a good shelf life if stored properly.

If you're going to line skip the WD spray I mentioned in my last post.

Por 15 is an import yes?

I have tried the wd40 to no avail, but i’m wondering if the 2 issues causing the most grief weren’t a) inadequate neutralising of acid & b) speed of completion.

I still thank you for the guide though!

Paint supplies stocks Por 15 products if you have one in Melbourne.

As for the flash rust after derusting, neutralising is key.

I had to leave a tank neutralising for two days and even though the neutralising solution came out orange the tank didn't flash rust. I then rinsed it out with a mix of acetone and metho, but metho alone will do. This also leaves the tank liner ready - assuming you have removed all fuel residue.

I remove the residue before the derusting as residue can put a film over the rust, protecting it from the vinegar. A solution of caustic salts truck wash will remove fuel residue.
