Prop Speed. 3 1/2 months in 80+ deg. Caribbean waters = no barnacles and very little crusty worm. When the boat sits for a week and a few of those pesky wormy things afix themselves to the blades, they come off with the wipe of a hand. The unprotected Dynaplate 8" behind the prop is covered with all sorts of crap.
The stuff works. I guess the question is do you want to pay for something that works as well as diving on the boat every week or so? I bought the $240 small kit. I've gotten three prop applications from it. Why not see if you can find others in the yard who want to split the cost?
Warning: if you DIY-it, make sure you have two people available and follow the directions exactly. Also, as with most things -- half the battle is in the prep. Don't cut corners there.

Today I applied two coats os Aquagard Alumi-Kote, color black. The can said it works on aluminum and other non-ferris metals. It semed to adhere okay. I might do a light sanding and another coat tomorrow.
I'll let everyone know how it works, but the bottom will be getting cleaned weekly.

|FarCry||I applied a product called Peller Clean by Seajet Seajetpaint in November of 2008 and just last week there were some very minor signs of fouling which were easily dislodged. This is the first time I've tried anything other than Micron 66 on my bronze two blade prop. Historically the fouling on the prop would require monthly agressive scraping within a year of a bottom job even though the bottom was still pretty clean. I plan to haul again in November 2010 and absolutley will utilize this product again. It is about one half the price of Prop Speed and came highly reccommended from both powerboaters and sailboaters.|

|brak||T37, your paint is white - or is this just an effect of a digital photo? The one I used is fairly dark gray. I wonder.|

Unfortunately, I didn't make it to the boat before they power washed the bottom, (I wanted a pic showing a more realistic result) but here is a shot of the shaft and prop (don't mind the cutlass ) after more than 12 months in the water. You can see on the strut where a few barnacles were, but otherwise its pretty clean. This year I will remove whats left and apply fresh, last year I just ruffed it up a bit and did a re-coat.

Um, sounds odd to me, but what do I know...

It takes me about 30 minutes to do a through job. I do not use any primer. I apply per directions 2-3 coats with in 5 minutes of each other in 60 degree temp. http://www.pettitpaint.com/fileshare...ds/1179320.pdf
The boat was just pulled today, the zinc paint was last applied March of 2009, the boat is keep in the water year round. I will take pictures tomorrow evening and will hopefully have them posted to this thread by Saturday. I can tell you that I have a 99% Barnacle free prop and shaft, you'll see soon enough. Most everyone in the boat yard uses it as well with similar results?
