Petit Barnicle Barrier

[Gregory S]

I want to use this stuff on my rudders, props and struts. What should be done to prep these surfaces. Should I do the shafts? Trim tabs? Not supposed to use it on aluminum, but the tabs are stainless?????

Let me know how it works.
I only get barnacles on the underside of my trim tabs and a few on my shafts.
No where else.

Take it down to bare metal, and put a couple coats on. It will look like gray water coming out of can, however adheres well with 2nd. coat. Couple guys up this way use it on tabs also with few barn's/

Over the years i've tried all sorts of inhibitors >they all worked ok. This past summer we had a barnacle explosion the likes of which i have never seen. I am coming out for a short haul in april. I am trying an old timers suggestion. I am adding cayenne pepper to all the paint. its cheap and it cant do any worse than stuff ive applied in the past.

Thanks guys. I'm assuming my Bennett tabs are stainless and not aluminum and I can use it on them?

I used outdrive paint on my tabs. No barnacles. I added cayenne pepper to my bottom paint. 6 years no barnacles...

I have heard about the Red Pepper thing, but never tried it.
My tabs are stainless steel also.
Barnacles get thick, just on the underside, not on the top of the tabs.
I sometimes have one or two barnacles on the bottom. But they come off easy.

 

[Dusty Rhoads]

yes, Greg they are. I say, because ours are, and realized when I drilled them to put medial and lateral fins on each.

I used the Barnacle Barrier on rudder (stainless) last year and really liked it. Pettit site says not to put it on too thick or it will crack. I did two coats. Because it is zinc, it leached away over the summer. I finished the season with 3 barnacles on the rudder.

Good stuff. I've used it and it's cheap. My driver who cleans the bottom monthly asked what I was using and he started telling his other customers about it.

If you add cayenne pepper in powder form you will end up with a sand paper finish. If liquid & too much is added you could alter the properties of the paint i.e. adhesion, durability etc, etc.

The PO of my boat used it and when I hauled the boat last fall, I was very pleased with the low amount of barnacle growth. I will continue to use it. Directions say to use 2-3 coats.

On the chesapeake and I've used the zinc coat a few years on shafts, struts, rudders and center of prop and works well for the cost, but still need to run the boat. On my tabs I've tried this, outdrive spray, and bottom paint. They all seem to have about the same results so dont think it matters.
