I've used interlux fiberglass bottomkote ACT over the past two seasons and overall have had good results...I intended to slap another coat over the existing layers (2 minus whatever has washed away) but after inspecting the bottom with a yard manager he informed me that I might be able to get away without painting this season. This sounds great in theory but after reviewing the Interlux website it is not recommended rather, "does not retain its antifouling ability for seasonal out of the water storage." As you can see there is a discrepancy here but I'm lead to believe that if I wash or sand the outside layer to expose the "old yet fresh" paint that I can get away without the labor plus bucks spent which equals me in the water even earlier. Has anyone else out there dared to ACT above and beyond what the label recommends? Brian H23 kickin' back Greenport LI

My experience has been....
that trying to get 2 years out of ANY of the ablative paints is a joke. I have not used the particular formula that you are using, but I have used Micron CSC, Pettit Ultra, and WM CPP. I have put on 2 coats of each type of paint, and without fail the second year performance was bad. I have had hard growth and grass. I have spent the off season both in and out of the water. The boat was always cleaned at the beginning of the second year. After many years of going two years at a time, I have come to the conclusion that multi-year performance is a joke and I plan to apply one thin coat each year from now on. Perhaps my experience is dependant upon my location- I have been in the Pawcatuck River in Westerly, RI, and in Bristol, RI. Rich

Listen to the Mufacturer
I know the maker want to sell paint but they also want satisfied customers. They spend a lot of time and resources in testing their paints. Go with the advice of the maker.

Micron CSC
I use CSC on my 98 H240. I keep it in the slip April to October. I keep it on a trailer the rest of the year. I apply two coats and it's good for 2 seasons. I sail on the lower bay out of Norfolk.

"ACT"ing Up
ACT in NOT a multiseason paint and is designed for one season use only.You need to get a multiseason paint (micron csc or similar) I think you can paint over the act paint with micron but check the label or manufactuer's web site.Not all ablative paints are the same.Your yard manager gave you some bad info or misunderstood what type of paint was on the boat already.

Two years from Woolsey Hydrocoat...
In Boston Harbor, since 1999, I've been getting two years out of Woolsey Hydrocoat, a multiseason ablative. I power wash on haulout, but don't do anything before splashing (on the 2nd year). The second year does get slime growth more than the first, but the hard growth is kept in check. This year I'm switching over to Interlux, Micron Extra which has a biocide. A few people in my area have indicated they get excellent multi year results and it keeps the slime in check, too. One friend put a red layer under two coats of blue on his original paint, and now he only touches up where red is showing through each year. Fair winds, Tom

The key is "seasonal out-of-the-water storage"
I interpret that to mean dry storage all winter (four to five months). That's probably long enough to dry or oxidize the paint (don't know which) all the way through and destroy its effectiveness. That's probably why the manufacturer recommends repainting. The newer ablative formulas are less sensitive to drying/oxidation and you may want to consider using one of these paints this time around. As Tom pointed out, a conrasting color makes it real easy to see when the paint has worn off. You will see the most wear at the bow and the leading edges of the keel and rudder. Good luck.
