Anti-fouling bottom paint, cleaning and prep for the season?
Ok, lot of detail here, but I want to make sure I didn't mess up my FS and that I prep the boat properly for the season.
I have a four-year old Scott (#5801) which I sail exclusively in the fresh-water lake in town. When I bought the boat new from FS, I had them apply anti-fouling bottom paint at the factory. I thought this would help keep the slime and tannin at bay. After four years of mooring the boat on the lake during the season, there was a decent amount of staining on the hull. I have not been happy with the bottom-paint since day 1, as it has been flaking off from the hull from the start, revealing shiny fiberglass underneath. The flaking initially started where the boat sits on the bunks on my FS trailer, but has continued to other areas. Small flakes no bigger than a dime, but these add up to whole areas with no anti-fouling bottom-paint at in many areas (a couple of 1 foot x 2 foot swathes).
Before i put the boat away last season, I tipped her over at applied MaryKate "On&Off" hull cleaner. It immediately removed the staining. Unfortunately, scrubbing with a 3M soft scour pad also continued the flaking of the anti-fouling paint but did not remove it all. Also, once the hull dried, I noticed that the On&Off had turned the remaining greyish bottom paint a faint green (I presume this is the acid in the On&Off reacting with the copper in the anti-fouling paint). It was never smooth, but now it is VERY chalky.
Did I ruin my hull? Or is this just cosmetic? I quick search on the internet yielded many opinions and possibilities, but no definitive answers. So, I am turning to my fellow FS owners for advice.
I am not sure what to do now before I put it back into the water. Do I just put her in and go? Do I need to have a professional remove the remainder of the bottom paint and then wax/seal the hull? Can I wax/seal over the greenish bottom paint?
Any advice appreciated.
