Paul, my bad, it's Loctite 480, it's expensive and Ebay is where I got mine from, buy one where they give the expiry date as it has a shelf life. I don't store it anywhere special other than on the shelf in my study
I think it works so well as it has a slight rubber trait which allows it to flex, unlike normal superglues which dry almost rigid. I primarily bought it to stick plasticard to brass, but it's stuck white metal hangers to the frames on the A3 and I've tried to break it off and the casting just bends, unlike superglue or 5 minute epoxy which all broke off with little effort.
Despite it having a rubber trait it is still very very viscous and easily creeps into small gaps. takes about 60 seconds to start going off and workable in an hour or so but full strength is after 24hrs.
Best
