I left someone to mount a Belfast sink to a base unit. It was mounted in
totally the wrong position using Evostik Nail and Seal. I finally removed
the sink, totally wrecking the unit and leaving loads of muck on the bottom
of the sink.

What is the best thing to remove the Nail & Seal from the bottom of the sink
before I fit it myself to a new unit?

By the way, I can well recommend Evostik Nail and Seal to stick anything to
anything. "That's f***ing Evostik Nail and Seal - buy it now it's really
f***ing sticky!"

Thanks in advance,

Martin
