Diesel-proof sealant

[Saltram31]

I used this to seal some urinals to the wall, was spec'd for by the customer. Didn't think it was that verstaile but having a look at http://www.ct1ltd.com says otherwise.

I was given a demo by the rep who worked for CT1. It is fantastic stuff, I carry a couple of tubes on the boat. I used the black to redo a couple of teak sections in my cockpit and found it doesn't shrink like polysulphide as it does not contain air pockets.

Duncan, I think you have hit the spot!
A 250ml tin seems right: the dab I was given came from such a tin, not a squeezy tube. I'm pretty sure it was not Hylomar (that's too cheap too!)
Thanks.

That is what I used to seal the lid on my diesel tank.

That was after I found that when I brimmed the tank the contents found it's way into the bilges.

That was three years ago and never had any problems since.

I think I got it on ebay.

Was not too expensive.
