But, I called a buddy up yesterday, who strongly advised that instead of sanding, that I repaint. So, I put a fresh sheet of 100 grit on my random orbital sander and took off all the drips, runs, orange peel and all the high spots. Wiped it down and then put a new coat on with a 4 inch yellow foam roller, but only about a foot at a time, while immediately following up with a foam paint brush (I think this is called tipping) Any bubbles are popped and smoothed down.
The picture above really shows the nice reflective shine
Unfortunately, I previously was pretty happy with the grey primer and thought that I would stick with grey, but epoxy primer has a tendency to be chalky after a while, plus it was kind of soft, in that it would show fingernail scratches, so I had to paint. But , the starboard brand of UV stable plastic that the rudder cheeks are made of are grey ( I could have ordered white, but didn't). So, for now, I have a white, high gloss boat and grey rudder checks.
