Antifoul or grease 290D/Ps what do you use

[boat193]

Hi All looking at taking the boat out for clean and antifowl in a couple of weeks, what do you use on your legs, i am in Spain, and all i am getting on the outdrives is a kind of white worm that goes hard, it scrapes of easy, but i have to do it every few weeks, any advice would be most welcome, thanks

I have used this for the last year & hadn't lost a knot in speed in 11 months until one of my fuel pumps started playing silly buggers last week. It really does work but must be applied properly.
