Paint

The "roof" over our cockpit is made of aluminum sheeting.  Over the years, it's gotten some corrosion and there are a few spots where the paint is peeling.   It's not really feasible at this point to remove the aluminum and strip/treat it since all the solar panels are mounted above.

So, we decided a little clean/cover-up would be good enough.

Sanded and scraped the areas as best we could.

 Brushed on a few coats of Rustoleum and the corrosion no longer catches the eye.  (The corrosion will come back, of course, because we didn't treat it.  But we'll just do touch up on occasion and live with it ).
