We are in an aggressive
salt water environment. Last year we applied a
cheap hard surface non ablative
paint and in 6 months were hauling the
boat bi-weekly to remove
barnacles not just algae.
Here is a picture of our first haul last year outabout 6-7 weeks after application. We noted
boat speed deteriorating and black smoke from the 10 hp
Volvo. You can see the difference between the cleaned and uncleaned part.
This year we applied 3 coats of Micron Extra (Blue) and an extra coat at the
water line and
keel. We looked at Micron 66 but I don't have that many boat bucks. Micron Extra has a "decent" price.
This system is advertised as self
cleaning ablative paint. It advertises 25-50% copper oxide as the main ingredient. It's longevity is determined by the number of coats and the aggressiveness of the algae. We have had it on the boat 6 months and have only hauled the boat once, because the uncoated prop was fouled.
I have dove on the bottom and there is nothing but a coating of "slippery" paint. I wiped it down with a dish cloth and have decided against further wipe downs so as not to accelerate the paint loss. The rag came out completely blue.
The only thing i don't know yet is how long it will last. I'll update the board but so far it's looking pretty good.
I am a very satisfied camper and have no other interest in
Interlux paints.
