Getting ready to add new/first antifouling coat
Hi all. I've has a '69 Cal 25 for about 2 years now that I've been meaning to polish up and re-christen, unfortunately Uncle-Sam kept getting in the way by sending me to the sandbox each year!
Now I'm back and I figure the first step, should be a new bottom coat. The Cal does not appear to have an antifouling coat on it (freeboard trim and bottom coat are the same color/tone) and despite its age, the existing coat is in decent condition...no flaking, just some chalky run lines from the oxidized gel coat (that's next!)
The boat will be moored in Seattle, Washington, in fresh water Lake Washington/Lake Union all year and will be used for day sails in Lake Washington and 2-4 day sails in Puget Sound (saltwater). The most obvious nuisance is the various milfoils that have taken over the bay.
From everything I've read, I'm thinking all I will need for prep is a light sanding, 80 grit wet/dry sandpaper, removal of the dust with a cleaner and clear weather. I've had two coats of Interlux Bottomkote ACT recommended, which I'll apply with either a pump-roller or airless sprayer.
Before I good in the wrong direction, I'd appreciate a sanity check on this. This is my first time fixing up a boat some I'm in uncharted waters!
The boat will be dropped back into the water January, as my wet moorage sub-let is vacating and I don't want to double-moor the boat, so I'm racing the temperature clock. Highs drop to only 52 by the end of next week so I'm hoping to apply the two coats on Sun-Mon (26-27 Oct) so that the paint will adhere well.
