Here is how it has held up. The Snow Roof bond continued to hold everywhere and provide a waterproof seal. The top coat of acrylic has checked after two years. These are very fine lines. So after two years I lightly sanded and repainted with acrylic house paint.
On the sides of the Zephyr I had two spots where the paint had lifted. I removed these blisters, sanded and repainted.
In my experience, house paint works OK for a low cost exterior
