Robin's bottom now is completely scraped of all the thick, old bottom paint. Next step is filling the voids where there were blisters, then sanding it smooth.

Below is Robin's bottom before it was scraped. The small white pebbles are actually barnacles. If you look closely at the lighter patches of red, you may be able to see the thick edges of the darker red bottom paint. I have said there was a quarter inch of paint on the bottom. It only looked that thick.
