Which reminds me of a joke...If you could relocate any part of a womans body, what would you move?

Yeh, that may well be correct. My understanding is that the adhesive is acidic and the acid prevents curing. Dilution of the acid and/or contact with an alkali will cause it to cure. I believe that's why a very thin layer is preferable while gluing because the substance being glued may not have enough moisture present to sufficiently dilute the acid to cause a cure of a thick layer.

The adhesive itself is not acidic. However water starts the polymerisation process - it is in effect the "hardener" if you think in terms of 2-part resin

I think you'll find it is and baking soda is a common accelerator. This info I got years ago (so I could be mis-remembering) when superglue was fairly new to the market. It was a poster I saw in BSL produced, I think, by Loctite and it gave an explanation of the curing process.

Right I've got a load of the grey Avon Rubbing strake now. Wanted black to match but picked up a job lot of new strake.
Would you attempt to take the black to fit all grey? Truth be told I'm happy enough with the black but I couldn't let the grey strake pass me by at the price.

I don't know too much about various formulations other than some being thicker and slower than others but I have experience of its ability to flex. I once caught the sidewall of a virtually new tyre on a rock. It peeled back a flap of rubber about an inch long and half an inch wide and exposed an area of the tyre cord. It was stuck down pretty much immediately using superglue and it stayed together for the life of the tyre. I guess it did a fair bit of flexing during its life and it would be subjected to the elements too.

You can probably tell I'm a bit of a fan of cyano and rubber.
