One thing to fix were little cracks on the cowl on both sides. These cracks were cause by the engine contacting and rubbing on the inside of the cowl. I filed down the two touch spots. They were high spots on the side baffles at the rear baffle.
I sanded and filled the cracks. Primed them and painted them. Then I had to sand the line and polish it smooth. It looks okay, but with a good eye and by tilting the light you can see the patch. But I like it fine.
