Washing the hulls
Since we had given the hull additional coats of clear resin to fill the fibergass weave, we had to wash them again to remove the amine blush in preparation for the final sanding and painting. That's how we spent three hours this saturday...

Deck seat painting
The last six days went in successive application of 3 coats for each side of the two deck seats. Here's the beginning
We then discovered that we do have a problem with this paint. While the finish looks pleasant and durable, the paint softens if soaked in water for several hours. So we have decided that we will use this paint only for the top sides, and accepted the idea of using toxic paints (most probably one part polyurethanic enamel) for the hulls and the appendages.

Deck seat washing and sanding
Five hours of work this week end. First we removed the amine blush from both sides
We then bored the 4 bolt holes using an oversize 15 mm bit to allow for coating with slightly thickened resin bringing the diameter back to 12 mm. To do that we used 12 mm bolts wrapped with adhesive tape to keep the resin separated from the steel. You could see the tips of the bolts protruding from the hole

Finally, we sanded and cleaned both sided in preparation for painting.

Forgot to mention...
...that since the second but last update I have missed to take into account the last coat on the upper side and all the three ones in the lower side of the akas. Moreover, today we gave the second coat to the upper side of the swing arms. So, the total working time is updated accordingly.
We have a problem with red paint. While the grey and the white ones are easy and pleasant to apply, the red paint appears of much lesser viscosity and is virtually impossible to use. I think there's a problem with the mixing machine and therefore we'll check with the vendor immediately.
