Respectfully disagree...
...with Tom's post. Primocon will probably work, but I think there's a better solution. If you search the Forum Archives on this site, I posted a step-by-step article about how to paint a H23 keel last (March? April?). The title of the post (and easiest search term) was "Interlux's Solution". I also posted the approximate cost of materials in that thread. I didn't include haul-out or yard bill prices, but I will be posting photos to the Photo Forum soon with those details. You can also go to Interlux's home page (http://www.interlux.com) and check out their boat painting guide- It will give you a good idea about how to proceed with this project. Enjoy your new boat! We have really enjoyed our H23.--Jon BastienH23 '2 Sheets to the Wind'H25 'Adagio'
