while in the mood for plugging reasonable looking companies I can across a guy (when they let me out of my exhibit) at the Sanctuary Cove Boat Show selling this stuff:
Hull speed super glide
http://www.hullspeed.us/hullspeed_products.asp#superglide
It looked rather neat. Very easy to apply, just use one of these basic spray bottles to apply to the surface and then give a circular wipe with a clean white rag. Being a 2 part system it will cure on the foil surface and is good for up to 3 months. It does not need to be buffed like a polish system, just wiped into a thin film.
It looks ideal for foils and apparently olympic dinghy teams are using it. Anyone else tried it?

$195 per quart kit and that would last you until you are grey and unable to race moths I should think!
