Time to stop sanding.

Several places on the boat are showing thinner places on joins, especially on the curves of the hull.

Same shot without the light behind.

I dont think that this issue is as bad as it seems.  There are still some filler stains and some uneven planks that need some further sanding.  I will need to sand lightly accross the curves.  At the moment I am using 120 grit and hope to move to 240 grit soon and then quickly on to Glassing.   Right now I will be making the bow and stern pieces.
