Nice frame and a really nice painting. You're right about the desert sun. Out here where i live, our altitude is between 2500 and 4000 feet (and higher into the surrounding mountains. So we get really intense UV radiation. 15 year exterior paint is good for about 6-7 years. Redwood fencing that should last 20 years look like ancient dried out wood in half that time. I really like the use of lapjoints for this very rustic frame Oliver. But I'm kind of a fussy guy and like those perfect mitered corners. We keep our eyes open for weathered wood objects and use them to decorate the landscaping in the back yard. A few years ago i piled a bunch of branches up near the back fance, today, they have "evaporated." Almost nothing left of the pile today. Really amazed me how that happened. I definitely try to stay out of the sun, particularly in Summer. The picture is a late afternoon picture of the visible part of my back yard, planted mainly with native plants or plants that get by on very little water. The little shed is an insulated shack over the drip irrigation control valves, not an outhouse. My shop is just off the the left of the picture.
The more I do, the less I accomplish.
