I glued in the inwhale spacer blocks, figuring they would benefit from being painted with the interior of the hull, with only the tops varnished with the entire rail assembly.
I put two coats of undercoat on the entire interior. It went pretty well, but the finish coast... well, we'll see. The first went on today, and it looks pretty sad. But i think i did 6 exterior coats before I ended up with an acceptable finish. The interior will me harder still I think.
