I also had a great run with Vivid on my 830, in the Weiti and cleaning regularly for racing.
I’ve just applied the same to the 930, by airless.
2 full coats all over and a third on the waterline, bow sections and foils.
Went back in a month ago, haven’t cleaned yet but a thin brown coat of slime evident top 100mm. Wipes clean with ease so hopefully will slide off when we motor out for the Enduro????
