Freezing the bait on the hook?

This is probably more for sea angling because I could not think of a bait or circumstance where it would suit coarse angling however, maybe!
It was a tin of spray that froze the bait on the hook so you could cast it hard a long way and it would not come off; once it was in the water for a minute it thawed back to a nice soft bait. It was in a tackle shop and cost £6, never seen it before.
I can see its potental for sea baits like lug and sandeels which I fish with. I have a good way of hooking sandeels but still have to be a bit careful when casting long distance. Any potential for coarse baits?

Plumbing suppliers stock various brands .
I used to use one for deadbaits in my piking days.
Very effective....

Sardines for pike fishing can be notoriously difficult when thawed out and can break up on the cast.
Big DIY stores do a similar product used by plumbers to freeze pipes temporarily to give time to do small repairs.
I would happily consider using it if I knew for definate that it's contents were harmless.
Great concept tho !
