Tank sealer KBS -V- POR 15

Has anyone tried or had experience with either of these products?

Are they comperable? I have used Kreem in the past. But never again.

I am hoping for a harder more durable long term fix.

Bets regards,

frp

I had pretty good luck with POR-15 but eventually
got the tank welded a couple years later when
a hairline crack finally re-opened. For a crack
near a mount bracket, welding was a better fix.

I had minor problems with a POR-15 buildup on
the inside of the petcocks and I had to open
them out a little so I could slide the petcock
and filter back in.

When it was draining, I'd left a cut open soda
can under the petcock to catch the last drips.
When I came back a while later, the POR-15 had
apparantly eaten into the aluminum can and
run off, making a small mess to clean up. It
seems to react strongly with aluminum.

If I were doing the job again, I might also
consider welding, brazing, soldering, a two
part epoxy or "red slosh" aircraft compound.
POR-15 would still be on my candidates list
though.

I tried the following on my tank after sanding the paint off and
enlarging the pinholes slightly. All failed.
JB Weld
muffler putty
body filler cream
two part epoxy putty that dries like steel, can be sanded and will cure
under water.

You might have also tried house paint, mayonnaise mixed with
yeast, fish scales and beeswax, etc.

Thank you for eliminating those four possible sealants from the list of
possibilities. Did you ever consider using a product that is actually
made specifically for sealing pinholes in gas tanks, such as Kreem,
POR-15, KBS, or any of the other gas tank sealants that are specially
formulated to be impervious to gasoline and alcohol?

Yes I tried the epoxy putty that was specifically meant as a gas tank
sealer and it did not work. Thats why I tried the other options.

Are you talking about the stuff that comes in a two-part stick
similar to modeling clay, that you mix together? If so, that is
nothing like the products I mentioned and I am not surprised
it didn't fix your problem. Kreem, POR-15, KBS and all other
gas tank sealants of that type are a liquid coating that covers
the entire inside surface of the tank. If you properly de-rust
and prep the tank, they cannot fail to work.

Yes, that is what I tried. My Suzuki had pinholes and a small crack that
was about 1/4" long at the back end of the tank.

I don't think there's any permanent fix for cracks other than
welding or maybe brazing. Whatever caused the crack will
keep flexing it until it opens again.

Seriously: As long as you are at it, try soldering too. Get a nice
propane torch, flux, solder suitable for steel like that made for
radiators, and have at it.

You may want to practice on a piece of sheet metal != a tank. You have
to clean/sand a much larger area and heat the work piece maybe 1"-2"
away from where you will actually make the repair to keep the surface
from oxidizing so the solder will stick.

I prefer to use an Oxy/acetlyene torch so I can deliberately run it too
rich and this keeps the clean part from oxidizing. You can do it with a
propane torch, you just have to keep the flame from the work area, kind
of like

Where you apply the heat. Where you folow solder. Hole
**** xxxxxxx OOOOO
As the solder melts and covers the metal, you can move the flame towards
the hole, but you never actually apply the flame there. If anything, you
circle around the hole giving it a wide berth and flow solder to the center.

Only if you can be sure that there are ZERO fumes in the tank. Flushing
it out with water, and leaving in the sun to dry for a week, is not good
enough.

Isn't the usual trick putting dry ice into the tank?

That would drastically reduce the temp in the area to be
soldered/brazed/welded and make it very hard to apply enough heat.
It would do nothing to reduce gasoline fumes so how does it eliminate
the risk of explosion? Are you suggesting that as it sublimated to
carbon dioxide it would totally fill the tank with it, and that it's
vapours are heavier than gasoline, so that the gas fumes would be
displaced out the top of the tank?
