Thread: KBS Tank Sealer Worth the Effort?

If the tank is leaking because it is pin holed from rust as my 110tdi and my previous RR classic did just spend the extra on replacement and get over it with confidence, i painted my new 110 tank on the outside with por15[not tank sealer] because its steel and rusted between the strap/hanger and i couldnt get a plastic one[td5 i believe?], in the past i have had a fuel tank[bmw2002]welded up and 2 motor bike tanks done with por15 US tank sealer, for your cost i would replace the tank rather than attempt repair when its not a rear or expensive part

I have used the POR equivalent in an old rusted bike tank and worked very permanently filling some quite large holes. However the clue to its success is covering the whole of the inside of the tank so it forms an inner skin.

You will need to take the tank out and pour the product in and then constantly turn the tank around in random directions until the entire inside of the tank is covered - even then it will have to be randomly turned until the sealant starts to go off to prevent pooling in one spot.

Justmixing up some redkote dry with acetone today for my series one.
I dont think its enough volume to cover the flat sides of a square tank so think I will order another can. Curved sides can probably be covered easier than flat ones.

thanks.

yeah of course a new tank is easier and pretty much guaranteed to give good service. I'm only considering a repair because the 90 with side tank was never sold here in Auz so AFAIK its not readily available at a good price. In the UK they are cheap but postage is more than the value of the tank itself.

Whilst I save money and recycle my tank with the KBS fix, I think its only worth it if I end up with a tank protected to last another 10+ years.

I think considering it has such a small/slow leak I may gamble and try the KBS... surely it cant make it any worse.

That is unless someone on here has tried the KBS/POR liner and been disapointed?

Hi mate , I think you'l find fixing a leaking fuel tank, is only a repair , it will get you out of truble . It won't last to long . It will let you down at the wrong time and in the wrong place . Look to replace your fuel tank , at least you'l have piece of mind ..Regards ,..jimr1 ..

The POR product is designed as a permanent fix and I have had no issue with it.

Dont know about KBS, but I have used Redkote, which is also designed as a permanent fix, and had great results.

Whatever you use, just, make sure you follow the instructions to the letter.

I've been disappointed with the POR one.
I lined a newly built tank (fabricated) & it started flaking off after a couple of years & blocking the fuel pick up.

This was done in 1995 so it could well have improved slightly by then (I would hope).
