This research project is funded by EPSRC Research Grant No. 98316366 and by International Coatings
Ltd. The large plate experiments at CEHIPAR were made possible by the European Community
programme CEHMAR, which promotes the mobility and opportunities of researchers. The authors
wish to thank the CEHIPAR staff for their contribution to the experiments. and Sabino Quirros and
Josu lntxaurraga from International Coatings Ltd. Spain for their help in the paint application. Trevor
Wills (Akzo Nobel Technology Centre) is thanked for his help with the optical measurement of the
surfaces. Dr. Townsin is thanked for his helpful comments and suggestions throughout the course of
this prqject.
