Sorry to report this one also has a small dent below the right side badge, so you wouldn't escape bondo. Besides, shipping would be more than the damn thing is worth.  >:(

Not to Hi-jack the thread, but how the heck do you guys see down in the tank?
On my 75' 550 K1, I really am hving a hard time seeing in there even with a good flashlight.
Do I need to stick a mirror down in there?

Regards,
DiscoEd

I have a mechanic's "Bendy-Light" that I can drop into the tank and peek around.

At work we have a fiber-optic scope I can put in there (after hours, with no one around, of course!). I know these are available, but damned expensive (over a grand)!

G'Day CBJ, no, I wouldn't use Bondo to repair a hole in a tank, (if that's what you meant?) I've just got a couple of tanks that after paint and bondo removal (I use a 3M nylon "strip disc" mounted to my sander/polisher on the top and sides, and chemical stripper underneath) are pretty badly dented, and I'm not that keen on cutting the bottoms out to bash the dings out from the inside.

I've got a mega-dollar "stud welder" that I can use to pull the dings from the outside, but I can never get them perfect without being able to "hammer and dolly" them from both sides. A little Bondo is fine for small surface dings, but in my opinion, that's about all it should be used for.

My (now rotten) F2 tank came from New York, and apart from non-OEM paint, looked great, but somewhere between New York and Melbourne, an errant Postal worker put his boot through the box and put a ding the size of your fist in the tank, so instead of my initial plan of just rubbing it smooth with some 400 and priming/painting it, I had to strip it bare, and lucky I did, there were two holes in the tank where a PO had used self tapping screws to pull a dent, then just filled the holes with bondo! Ok on a car panel perhaps, but disasterous on a gas tank!

Bottom line I guess, is that if the holes are too big to be repaired with leak sealer like POR15 or Kreem, then you may as well junk it. Remember that gas tanks rot from the inside out, so pin holes on the outside don't equate to the damage you'd find on the insides if you could get in there and see. Cheers, Terry. ;D

Couldn't agree more. Even if you were to try and pick around on the outside looking for weak spots, unless you are lucky enough to hit the paper thin rust, you won't find them. All future used tanks will get a phosphoric acid test and let it do the testing for me.

cbjunkie,

Thanks for the reference to The Must for Rust. A year and a half ago did my orig. tank with the first two steps of the POR-15 kit which uses phosphoric acid. Worked great, but the kit was about $35 and really all I used was the cleaner and acid. Checked out Must for Rust at Home Depot and it is phosphoric acid as well and only about $6. Though it did reveal some holes in the tank  >:( it worked great. Afterwards, rinsed real well and just let it air dry. Finally got around to uploading some pictures. Top two are the before and bottom the after. Pretty impressive stuff for the price.

ha-ha, right on! full circle, bob - i bought the P-15 kit after you recommended it on your site - i already was using the MFR on the 350 last year and didn't make the connection (i did NOT bother to read the ingredients  :-\) until i actually poured out the POR-15 stuff into my tank...

i thought, "hmm...this looks, smells, and acts just like the MFR stuff..."

those photos say it all...my "new" SS tank from ElCheapo is on its way right now - I hope it makes it by this wkend...  ;)

Hey CBJ, before you take the hammer to it, I'll send you a couple of pics of an F tank that Carpy converted to a real nice "Cafe" tank by cutting and welding "Knee recesses" and a K series filler, it really changed the look of the tank, without the requirement for a bucket of bondo, ha ha! I've got the pics on a CD he sent me, I'm "pliagarising" the look for a tank I'm doing for Sean Condon, but am upgrading it with a modern Yamaha R1 style flush filler cap. Cheers, Terry.  ;D

i've seen the cutting and welding jobs he does - and they're very nice. if bikes were the center of my universe (shock! awe!) and my means of sustenance then i would definitely apply my craftsman's touch to the process this way... ;D

here's what me and paul are up to...

http://www.sohc4.us/forums/index.php?topic=6254.0

first paul's - the inspiration...
then mine - the first (failed due to pinholes) attempt...

but do send on the Carpy photos, Terr - maybe you have some that he doesn't have posted?

HELLO ALL - I am new to your group but certainly not new at what you guys are doing - I may can help on this one - I have sealed "dozens" of tanks over the years & have tried pretty much all the brand sealers mentioned here - all appear to worK "ok" buuuut for me this is the ultimate sealer & it is cheaper  @ about $30 a full quart - i really like the fact that it is silver not funky green like some - once applied your tank still looks like silver metal inside not gummie bear green
check out their sight ----

Man CBJ, I'm glad you caught that... I went to page but didn't scroll down there.  :-[

This stuff does sound interesting for project "Fender"

Well, that is troubling! I guess that means I'll have to paint the fenders on my 550 twice before I pass it on to DiscoEd Jr.
By then the bike should only be about 80 years old.

I gave the "The Works" a try last week and boy does it work.  I had similar "before & after" results as Bob W's posted pics.  Problem is the rust came back immediately -- within 24 hours.  It was probably my fault...I think these 2 things contributed:

I was judicial in the use of my wife's "borrowed" hair-dryer for fear of breaking it, and I tried to immediately fill the tank with gas to keep prolonged exposure to air, but I found I had a leaky petcock, so I had to drain it, leaving it more exposed than I would have liked.

So, today, I try again.  This time I bought my own cheapo blowdryer from Big Lots, fixed the petcock, and on a suggestion from a mechanic, I'm gonna give the tank a good soaking of WD40 after the drying cycle.

Any suggestions on process and procedure before I jump in again are quite welcome...

fogging the tank with wd-40 works pretty well and you dont need to wash it out before filling with gas.
