Gas tank repair
I don't know if I'm in the right forum, but cant find a better choice.
The gas tank on my 69 cutlass S convertible has pin holes leaks under the straps. I need a quick fix to get me going temporarily until I have the funds to replace the tank. Preferably without having to drop the tank.
Any potions, compounds, mixtures or techniques that are tried an true?

I don't think you are going to be able to fix it without dropping the tank. And, dropping the tank isn't that difficult. The hardest part is removing the sender unit.
I ended up just replacing the tank on my '68 with a used tank from a '68 Cutlass in an "old car" junkyard. I understand that the new Canadian gas tanks are pretty good, too, and prices are reasonable. If you get a new tank or get the old tank repaired, you will most likely need to have a shop (usually a local radiator shop will also work with gas tanks) do it. If you buy a new tank, the shop will have to remove the fill tube from your old tank and install it in the new tank.

Rockauto has your tank (GM34C) for $114.79. These are the really nice Spectra Premium tanks that most show cars have.
This is alot cheaper then your car going up in flames from a leaky fuel tank.

Hey guys, on a 64-65 F-85 A-body, I bought a new tank from Canada, thanks RCORRIAN5 for mentioning this; It also has the correct placement of the neck where I understand in some cases from other mfrs. it has to be TIG welded to fit your application. If there is any interest I can go through my receipts and locate the MFR. I bought it direct no through a distributor.

He wants a temporary fix until he can get a tank guys.
Drain the tank, clean up the bad spots with sandpaper until it's bright shiny steel, use a paper with some grit because you want some roughness to the surface for tooth. Go to just about any parts or hardware/Home Despot and get some J.B. Weld and mix it up and slather it over the holes, leave some thickness and feather the edges. Wait a day and it should hold, an incandescent trouble light just sitting on the ground under it will help it cure faster if it's cool outside, the longer you can wait the better.

I agree with Bluevista above, but would add that in my experience, when I've had a tank with a few "pin hole leaks," a bit of wire brushing has revealed a far more unpleasant reality below the surface.
Yes, JB Weld it, or use a different bubble-packed epoxy putty made especially for gas tanks (more expensive), but expect to discover that you're looking at the tip of the iceberg, and remember that the tank's really not that difficult or expensive to replace.
