Coaming and lip

I put the first layer of the cockpit coaming on today:

Here's the plan:
The forward-most part was done with a smaller piece, and the side pieces were long, without too much curve. There's always a loss of material when cutting out pieces like this, but there's enough here to complete the job, with probably some left over.


The deal is, this stuff will bend nicely if the outside of the curve has been lightly glassed. The epoxy resin is quite flexible when thin. The foam compresses on itself, making itself denser and possibly stronger—if that makes any sense. If you try to bend it with the glassed side on the inside of the curve, the glass just cracks and splits in a straight line as the stuff folds neatly in half.

Here's more foam-bending goodness:
I measured and cut long, put each bend in gently in sequence, then cut the ends to match.
The bends need to be forced into the corners, but once there behave well.
That aft hatch opening reminds me of a submarine. . . Maybe I should paint it yellow? If I did—and that's a very big "if"—it would have to be a bright, rich yellow, like this:
