Where exactly should the hinge be brazed?  Mine wasn't yet a problem, but an ounce of prevention...

Thanks for all of the tips, guys.  So if I'm getting this right, plug the outside tubes and let the POR-15 do its stuff.  No POR will enter and plug the tubes because of the sealed outside ends?  Any suggestions as for what to use to plug the filler and sender holes?

I didn't realize that there was a 60 day wait for curing!  Good thing it's only March!

Plug the tubes on the outside.

You can use short lengths of vacuum tubing (edit)and some screws(edit) available at any auto parts store. You'll need some 5/16" and some 1/4". Remove them each time you rinse.

The fuel sender hole needs to be blocked off too as does the filler opening for both the wash and the etch.

Tape will not work well on the large openings.

You don't need to block off the filler opening (edit) or the tubes(edit) for the sealing process if you're careful. (edit) The sender opening should be taped, as well as the drain if the tank is equipped with one.(edit)

If you follow the directions exactly the POR kit works great. (edit)It's a 3 step process and requires some plugs/caps for the tubes and ingenuity to block off the large openings.(edit)
I modified my post here to try and clarify. If you have any other questions ask away.

The POR does not need to cure for 60 days. Sixty days is a general time frame for fresh urethane to reach full cure. It can be affected by many factors. You also don't need to wait for the finish to reach full cure to use it. Just be aware you can't wax it until full cure is reached.

The hinge need to be brazed around the plate that is spot welded to the tank

ducpainter im going to listen to you and am going to wait and use the POR 15 kit once the paint job is dry enough. Above you said this "You also don't need to wait for the finish to reach full cure to use it. Just be aware you can't wax it until full cure is reached. Were you talking about the POR 15? Does that mean i dont have to wait the full 60 days before using the POR 15 kit? The tank will be sitting in my room, its about 70 degrees in there with the heater on all day. If not 60 days, how long til i could use the kit and not destroy the finish?

I really can't answer your question.

You are trying to do things backwards and I have no idea what your painter did.

There are only two ways to remove POR sealer from the finish...solvents or sanding.

The acid and soap will also mark finishes.

If you have a gloss finish it's easier than a matte finish...you can't do anything to those.

If you get the soap or acid on a gloss finish those marks will polish out.

If you get the sealer itself on it you have 2 options...solvent while the POR is wet, or sanding and polishing if the POR has dried.

A fresh finish doesn't like solvents.

I'd suggest you buy the kit and read the instructions. It may help you decide the best options.

Hi Guys,

Sorry for the slight threadjack, but I'm getting a new tank soon, and would like to know how to prepare it to prevent all that leakage (that's one of the reasons why I'm gettin' a new one :)). How can I reinforce the hinge? Are there any pictures to illustrate this? And I guess I should be using the POR sealer after reinforcing, and before painting, right?

Thanks a bunch!

That's a fantastic shot.  Shows the plugging of the two tubes and the sensor hole as well as the brazing of the hinge.  Now if we could see one of the filler hole plugging... :-X

Do you want me to come over and do it for you too?   ;D

That's a carbie tank.

I just use an appropriate size rubber stopper.

That's very generous of you - sure, c'mon down ;D ;)

These things are new to me.  While I can usually grasp new concepts easily, the importance of "doing it right" is underscored by my feelings for the bike.  This is not the first time that my Ducati has let me down.  The flaky rockers, bad fuel sender and now a rusty tank.  All from a 2004 model year "Premium Product".  I'm living with it for now because of the fore-mentioned feelings, but really;  Come on...  this kind of thing over and over gives me a new perspective on the emotional attachment I and many others feel for these bikes.  So really, I appreciate all of the excellent advice that I'm receiving from those that have been there.  I'm just trying to retain the excellent care that I give this bike.  I'm going to "do it right". [thumbsup]

It would be cheaper for you to ship me your tank.  ;D

I'm sorry you've had some bad experiences with your bike...

but It's not rocket science.

If you can braze and figure out how to plug the holes in the tank, and read the directions on the POR kit...

it's been done right. [thumbsup]
