Worth having a good look around International paints web site:
http://www.international-marine.com/default_main.htm
Blakes are the other main marine paint manufacturer, also do a search on here as Tim M and a couple of others have painted hulls recently. Do let us know how you get on. Used the grey non slip inthe past and its very effective, safe to walk on in bare feet, doesn't get to hot and easily touched up without fading.
