Good on you M-Dog. Interesting to hear someone has tried it, can actually recommend a product and that the idea has been around for ages.

Whip that tube out and take it round the block pronto, what are you waiting for?!

the spokes should not move, therefore may not ever need adjustment again. (theoretically...

I think it could be theoretically because it assumes that spoke loosening only happens at the now sealed up nipple. I have a feeling a spoke can simply 'stretch' along its entire length. Dont they normally break at the hub end? i cant remember.

Not sure Woody's is still doing it is he? See: WoodysWheelWorks.com - under KTM 950 Wheels
He mentions the complexities of sealant and centrifugal force which occurred to me earlier.

I would rather put my trust in the tyre companies than someone who has tried a bodge and got away with it.

Ian, we're not talking about messing around with trusted tyres but sealing wheel rims. The tyre is not affected except that it now runs cooler and deflates more slowly on puncture. In the old days what has come to be known as 'adventure motorcycling' was all about what I call 'bodging' - aka experimentation.
Of course a proper tubeless rim would be best to save all this messing about with 3M gloop, but on the sort of bikes I like they are rare at present. I was sceptical about tubeless on bikes for overlanding but am now converted enough to give it a try. As we all know punctures are the most common breakdown we'll experience on the road. Decent proven TL tyres like TKC80s exist so IMO it's time to make spoked rims catch up with 3M or Tubliss.
