Yes, I'm sure E.Wood are having a rather good time at the moment.
I did a search over the Christmas period on 'Copon'. It is rather interesting. There are numerous suppliers of the product and application who have to be government accredited to apply the product. Saw some fancy pictures of water containers prior and post treatment.
Do a search - seems that solvent based solutions are not acceptable anymore and polymer based solutions are the future.
Torday and Carlilse's remit is to invest in undervalued companies, bash them in shape and sell them off. If the end game is still to sell off E.Wood then there will be plenty of takers imo.
