Re: [bolger] Re: latex paint for boat hulls.
- Thanks everyone,
..for all the responses to my questions re the latex/acrylic paints. My mind is at rest with regard to the use of the '100% acrylics' on a boat hull.
I also had a very quick and pleasant response to an email sent to Dave Carnell last night. His reply is copied below:
Latex just means water-based. Acrylic is the latest generation and by far the best. Hope you enjoy the boat. I'd appreciate hearing about it.

- What we in the US of A, including Dave Carnell and Jim Michalak, call
"latex" paints don't have any latex in them! The recommended "latex"
paints are 100% acrylic water based "emulsion" paints (I think that's what
they call them in Old Blighty). Look for that 100% acrylic on the label
and you'll be fine.

- Quite right. And to add to what the perspicacious Mr. Kohnen said: It's also true that oil-based enamels dry harder and more impervious to moisture transfer than the comparable acrylic latex. The trade-off is that they do eventually get so hard and brittle that they crack... and need to be stripped before recoating - but that's many years later, when one uses a quality paint.
To get back to the original question about the appropriate paint for dagger boards, rudders, etc. - I would not use an acrylic latex for those applications. At the very least, I'd use an oil-based enamel. I used an oil porch & deck paint for the foils on our Puddle Duck racer. But, far better would be a 2-part polyurethan - such as is available from Interlux or Epiphanes. Of all the surfaces on a boat, the foils are subject to some of the roughest use. A hard, slippery paint will be much appreciated over the long haul.
