Moving on and reverting back to the thread's central theme....
Having used (or seen used) the lot at some time or another....
'Stop'n'go', Rats Tails, Gloopy spray stuff in an aerosole canister.... the list goes on and on.... They all work reasonably well within their limitations and the limitations of those employed using them.
The best? Just like helmets, tyres, gloves, flavours of icecream (and even Marmite) it's all a question of individual taste...
Me? I like Crafty Plugger...

Why? Well, let's see:
I liked the name.
They come from Essex (salt-of-the-earth, biker mate) so are far removed from the global corporates, US importers, TouraTwat and Nippy.
Nobody else seemed to use them, so I stood removed from the common herd, a beacon of biker independence and selfreliance.
The tube they come in is smaller in volume that the alternatives. If it's small enough you will (probably) take it with you, as opposed to you thinking "I can't be arsed to add that to my voluminous panniers, full as they are of soft fruits" and then leaving it in the garage.
They work. Nothing more, nothing less.
For everything else, there's AA Recovery.
