I used Veridian a couple of years ago and its proved quite effective - I'm able to brush off all growth during the season with a soft brush. However, it tooks ages to prepare for painting and you have to apply a primer and allow a specific amount of time between coats - about 2 days work all in all. Its also quite soft, so it gets damaged easily & no good for prop. Overall I'm quite pleased with it though.
International do a spray on one. Its clear so you still keep the original look to the drive. Can't remember the name of it at the mo, but someone will remind me.
I hate seeing antifouled legs using "trad" antifoul.....it looks bloody 'orrible.
As Bob mentioned, for the last couple of years I have used International Paint Veridan product (£55 per stern drive).
It is a pain to apply and a lot of preparation is required, however no fouling throughout the season and just a occanisonal wipe with a cloth. I know Bob has mentioned he does not use it for his props, well I do and it does not come off - the biggest thing to watch is the Liftout a pressure wash (you don't on Veridan).
Like I said the key for this to work is a good rub down and preparation, especially the props.
My boat is just about to be lifted out and hoping not to apply a new coating - it should last 2004 season.
Erm think there may be a good reason not to use "ordinary" a/f on alloy legs,but cannot for the life of me remember what it is.Ho-Hum..........
I used Blakes Lynx last year.Neded two little tins @ 15.00 each per outdrive.
<hr width=100% size=1>If it aint broke fix it till it is.
Don't use an antifoul that contains copper, the ally will corrode being the less nobel metal.
International do antifouls that are suitable for outdrives, I use Trilux (white) and don't get any fouling.
Not wanting to start a riot on here. I know Happy used it on his volvo drive. All it did was give it a very slight bronzed pearlesant tinge.......I just know I'm going to regret that!
