Since my last post I have receieved a telephone call (and it isn't even 8.0am) with a little more information.
Allegedly Daniel Welford, who does not appear to be a member of the NCCA, did some work for an NCCA member Company back in February 2005 on a sub-contract basis.
Problems arose which were more involved than the mere drying times mentioned in the original post, a complaint was made by the customer and consequently, after NCCA procedures had been followed, a letter was sent to the NCCA member Company suggesting that a refund of money would resolve the situation.
It would seem that this letter may well have been passed on to Daniel Welford
The plot thickens
