I used Eco-clad this last haul out due to the large amount of algea growth in Charleston harbor due to the fast moving tides. I would have normally gone with Petit Ultima SR-40 but I did some research in the Eco-clad and it seemed to be a better choice. I think we may be one of the few boat in this area with this paint.
When I hauled her out last fall I had the hull blasted to the gelcoat and had all the blisters ground out and epoxied back and faired out. I went with two barrier coats two sealer coats and one coat of the Eco-clad. Only one coat because of the high build epoxy application. My painter really hated putting it on because of how thick it was. It took a few days to dry and the patch spots after the blocks were moved did not match very well. I was not impressed with the look of the paint after it was applied. The over night dew would leave streaks in the paint before we relaunched. I had a factory rep come out and she said it would dissapear when it got wet after launch which it did.
I have only cleaned the bottom three times since November and it seems to clean very easy per the diver. I will be interested in how it holds up on the next haul out next year. It is supposed to last up to five years (yea sure) Check out the pics and you will see the color difference wher it was re-touched after moving the blocks.
Here is a link to the Ecoclad folks.
