Title: plugging tank holes for anti-rust treatment?
Post by: Mandres on February 23, 2006, 04:53:04 PM
I've ordered a POR15 kit to clean and coat the tank on my '00 GS.  What should I use to plug the petcock holes?  I don't know what the cleaning and etching agents are but I'm guessing phosphoric acid and I don't know what kind of plug would stand up to the process.  Any suggestions?

Thx,

Any type of rubber or silicone plug should suffice. The acid will attack metal before it works on rubber or plastic.

When I por-ed my tank, I just used duct tape.

I don't wanna be a "search" fascist but one of the venerated ones, Srinath, I think has posted a lot about this, in fact he has a post in FAQs about it. I am pretty sure there is info also on some of the Gurus home pages.

I used black electrical tape with a high degree of success, but one dismal failure.

CLICK HERE (http://home.bellsouth.net/p/s/community.dll?ep=331&folderid=208550&groupid=41309&folderview=thumbs&ck=) for an abridged photo session of my POR experience.

The POR kit comes with a bit of shiny perforated towellette stuff that is basically a bandage for any holes you have in the tank. Use it as instructed and you won't have a problem. POR cures v-e-r-y s-l-o-o-o-w-l-y. So don't worrry about a fast set up time. The stuff is like a cross between ancient paint and cold syrup.

I cleaned the taped point very well so the tape would stick well. Just leave the filler hole facing up for venting. I also rolled my tank around upside down to coat the top, outside of the fill neck, etc. The POR kit comes with a disposable foam brush you use to coat the inside of the fill neck and to use on the bandage, if needed.

READ THE INSTRUCTIONS 3 TIMES, WAIT A DAY, THEN READ THEM AGAIN TWICE. I exaggerated, but seriously, read the instructions FIRST.

More tips with POR:

COMPLETELY dry the tank. Use a hair dryer or something similar. Run warm, forced air into it for an hour or so with liberal shaking to loosen pockets of water.

FIND CLOTHES FROM A DUMPSTER (DUST BIN to Cal,  :) )  TO WEAR AND WEAR DISPOABLE GLOVES AND EYE PROTECTION.

After the stuff has hardend - wait 5 days before messing with it. I used a tap to clean the threads of the pickup mount. If you have a film where the tape for the pickup was, the hole for the mount is easy enough to clean out with a craft knife.

POR is tough. You can't tear a thick section of it with ease.

Good luck!

Take your time for the curing part and follow starwalt's tip.  Also, get a pump to help get the water/acid/alkali whatever out of the tank quickly when you rinse/prep the tank.  A hand pump for gasoline will do.  You can get one from an automotive store for a few dollars.  Have a way to dry the inside quickly, e.g., an air dryer.  Then have another way to dry the inside for days, which I rigged up a space heater with some cardboard and stuff (emphasis on rigged).

Also, as Cal said, a lots of posts and time have already been spent on this subject.  A search will turn up all the information you need plus more.  That's how I went researching for my POR project.
