I decided that before I got hull panels installed, I wanted to do as much inside finish work as I could while access was still easy. So I started out by rolling on the final coat of epoxy on the bulkheads and other interior areas.
Everything looks so shiny and nice!
I thought I was good to go and could proceed immediately to painting the interior spaces white.
I had purchased some porch and floor white enamel for this job, but it was a latex paint, and I just felt more comfortable putting on something oil based, so I returned what I had and purchased Rustoleum Gloss White for the job.
To make sure I was getting good adhesion, I painted a small test patch, let it dry, and then was disappointed to find I could scrape it off with my fingernail. <sigh>
I sanded up another area with my random orbit sander and painted a test patch there, and found I had much better adhesion. But I couldn't get into all the spaces with my power sander, so I did a third test patch, just removing the gloss with a 120 grit sanding sponge. That also worked well, so I proceeded to sand all the gloss off my latest coat of epoxy by hand with the sanding sponge.
With everything dulled up, I can start on my painting after cleaning up the dust.
