Rust is Iron Oxide. Water creates a situation where slow moving oxygen bubbles are kept in contact with the iron atoms for extended periods, it's not the water that causes rusting, its the disolved air. Therefore, if you make an iron compound ready to bond with something, which is what metal ready does, there's a chance that the exposed iron atoms will spontaniously combine with the oxygen atoms in the air. Flash rusting. You don't need wet air, you just need air, which you probably have over there

here ends today's science lesson. Next week we will be studying how to make things go bang made from common kitchen materials and what voltage it's safe to expose your little brother to without causing permenant twitching and stuttering.

 

What do the instructions say? I forget, but it was definitely longer than 20 min. I had a heat gun in it the whole time in between steps too. I want to say it was at least an hour and it was hot as hell outside that day, so the sun was helping as well. I was building my deck and doing the tank here and there while I took breaks. I also made sure to get all the excess out of it. I propped it up, after coating the whole inside, so that it would pool up in the back corner behind the petcock hole and then tilt it to pour it out of that hole. I did that about 10 times or so leaving it site for 5-10 min each time.

 

There you go! Finally, some useful info that we can all sink our teeth into!!
Is this a great site, or what? :lol:

 

Koolaid.. I think your problem was that the tank had some water in it.. The instructions say that if the tank is wet, the liner won't bomd properly.. I don't think it's anything to do woth how long you left it on each side etc..

I left the bike 2 weeks without petrol in it after lining the tank because I was called away at work and when I got back it was all dried and cured.

 

I don't think I had any problems at all. The liner bonded just fine and looks GREAT on the inside.

 

Sorry mate.. Getting you confused with PerryFager

 

Good leson for the day. I'm eargly waiting the voltage lesson

I did the forkes today on my XJ went pretty well. I used the guide here http://xj650.blogspot.com/2009/01/how-t ... ll_04.html Only issue I ran into was on the right side forke. I kinda bent it while pounding it in with a large socket. So we'll see how long it lasts before it leaks. The oil in the left fork was vintage 81' 30weight by the look and smell of it... lol... the right fork had what looked like rusty water in it.

I also cleaned my tank out with the Metal Ready. Um.. there's more rust in the tank now than when I started and 2 pinhole leakes on the right side of the tank. I was able to get home, but my bike started leaking pretty bad so I had to drain the gas. Before I left my friends house I put some gorilla glue on the holes and covered it with packing tape. Yeah.... apparently it dosn't work. I think I can patch it with something in the POR-15 kit. Going to have a look at it tomorrow.

Forkes right off the bike


Rusty water/oil?


1 Dollar to the first person to take a drink

 

Ummm. If you look above, you'll see I said that Metal Ready will cause flash rusting. Twice I think. You shoulda used the Marine clean.

As it is, I'm guessing you'll need to get ANOTHER POR15 kit and do it properly, all the way to finishing with the sealant. I wish I had shares in POR15 lol.

Try using the Marine Clean on your tank, it should help a little, and stop the rust getting worse at least. But wash it out with water afterwards, before you put any gas in there, and make sure it's dry.

Don't try doing the whole tank seal thing at this point, you'll make a bad situation worse, although you canpatch it with the tanksealer and the cloth you got.

 

crap... must have grabbed the wrong bottle when I left. lol that explanes why theres more rust in my tank and my friends now than when we started...... oh well, I can get another bottle of marine clean if I need it.

So Metal Ready the tank, let it dry, use the cloth and liner to patch the hole..

hopefully won't dig myself into any more holes on this project....

 

Lol. We all dig holes. It's how we get out of them that counts.

IF you put Metal Ready anywhere near metal, then the next thing you need to do is put the POR15 sealant on everywhere that the metal ready went (or some other rust resistant compound). Marine Clean will help get rid of the rust you currently have without making thing worse. The marine clean is acidic, it eats rust. The metal ready is alcaline and it exposes the metal to bond with something. It enhances the bond with paint or the sealant making it grip the tank harder.

You know you can reuse both of these don't you?

 

Waite a minute. I used Marine Clean, just cheked in the garage. I still have the bottle of Metal Ready. I think I did it right then. I marine cleaned my tank and a friends yesterday. but they still rusted a bit more. Must have inhaled some vapors or something cuz I think i'm loosing it......

 

Lol.

You tank probably rusted because you exposed fresh metal to the atmosphere, same happensif you dip a copper coin in coke, it claens it, but then it tarnishes very quick. If you had used Metal Ready, it would be worse. I really think you should use a sealant on it.

 

I'm half tempted to put a liner in it.... Although I've been running it with chunks of rust, a pannel clip and a washer in there; so far the inline fuel filter has filtered out all the rust. We'll see how it goes.

I patched the holes in the tank just now. I used the POR-15 liner and the cloth it came with. So hopefully in 4 days it will have cured and sealed my tank.... fingers crossed. Its going to be a long 4 days with no riding.......

Heres a before shot




2 perfect rust holes


After with the patch
