each year (ie now) i think about the antifouling bit as mine stays in 12 months a year and the bleaching bit is a pain but i do have the luxury of being able to lift mine out with the works crane to spray it.
the anti foul idea stalls with me due to the need to sand up the bottom loosing all that nice polished gel...then degrease it, then prime it all up ,then antifoul it..and the biggest bit is getting the waterline straight !!
then the cost at my prices primercon is £30/ 750ml and 2.5 litres trilux is £80+
whereas 2 litres of domestos is £1.50 and an hours spraying
i did my old 5.5 delta and did the sand prime and antifoul and the first year it all fell off
apparently the reason was i didnt degrease the hull so the wax in the moulds threw the paint off.
after the 2nd year though the antifoul stuck fine and also without any more primer.
i used white on the white hull but after a while it goes slightly off white so you do see it.
i have read about clear antifoul but never seen it advertised. but i would imagine you'd still have to key up the hull to put it on.
may end up doing mine yet as she is up for refit at the mo'
