Paint mixing

Now is the exciting time when my one design boat is starting to take shape after a major rebuild and epoxying and I can start thinking about what colour to paint her.

I need to use two pack paint but the colours available are rather limited. Does anyone know of a company who would mix a colour for me...a bit like going to B&Q for your emulsion paint?.....The boat is only 15ft so It's not like a major order.

Thanks in advance for any help.

What's your boat?

Out of interest, what do you mean by ..epoxying?

The boat is a Wivenhoe One design...15ft clinker boat, built in 1935. Currently she is undergoing a major re-build including the replacement of all the ribs and deck. By epoxying, I mean that she is being coated in epoxy resin (West system) to ensure that she lasts another 70 years.

Thanks! I appreciate your original post was to ask for advice, and here am I asking you all the questions. I'm a new owner asking about your epoying process, because I always thought wooden boats, specially clinker built like yours (and mine), had to somehow breathe and soak up water to make the planks swell and seal together.

Doesn't epoxy just cause problems later - once damaged or cracked, or just in the normal process of expanding & contracting, the epoxy might let water in, then rot?

You're quite correct, Tim, in thinking that clinker boats built from solid wood, as opposed to plywood, need to take up water to swell and thus achieve a tight hull. Coating with epoxy will inhibit this process. Epoxy coating is alright when the planks are plywood, because the plywood is dimensionally stable in all directions, and the laps are usually glued. Solid timber is anisotropic, which means it expands and contracts differently in different directions. While epoxy is unlikely to allow water in to cause rot later on, the water can get in in places that are not coated [ie, the laps and behind ribs] and then have difficulty in getting out again where it has spread behind the epoxy coating. All in all, I don't think that I would advocate epoxy coating an older clinker boat.

The joy of this forum is reading posts by people who understand specific areas of boats and boating, and who can post short, authoritative and clear views

Back to the real question. We needed an out of spec colour for Zuline - International wouldn't mix it so we experimented. The colour we wanted was in their single pack range - a richer yellow. We got a large piece of white card, a small tin of red and a small tin of yellow and went for it. The result is a really rich strong yellow at a ratio of 1 red to 30 yellow. I assume that you could do the same thing with two pack. Also two pack will crack if the timber moves - something softer is better usually on timber.

BTW Peter Duck you can see the colour we got - look for the new yellow boat in the mooring field up near Hobbos.
