I tried to apply from top as well but it didn't seem to want to work it's way in (very tight fit). Obviously apply from beneath would require quite some quantity to allow hollow post to fill up before it making it's way in-between post and frame.

In the UK it is difficult to get hold of ammonia, not sure why? Belive it could be used in making explosives? Do not think drug usage is the reason? Managed to get some 9.5% strength ammonia after trying several chemists and as far as I understand anything above 10% won't be available.

I have investigated grease, paste, etc. usage on carbon and many people seems to think this brakes the CF down?

Anyway, at this stage it seems to be a problem for the future but will seek advise at LBS.

Thanks for your answers.
