I have had it up for 7 years in Phoenix. Even the west walls have held up well. I had badly alligatored paint before - sanded and primed and covered with Duration and it still looks good today.
Its expensive, but if you don't like painting, a good choice. Monica
Wow, I was just about to post this same question and ran across this old post using Search. I need to have my fascia at the ends of my house done. Not an easy place to get to, and pretty much all the paint is worn off, making my house look horrible there. So I only want to do this one time. It will be worth the money. Thanks.
Coil stock is a roll of colored aluminum, that is bent with a tool called a break (brake) not sure which spelling is right for this. Your trim would be wrapped in this bent aluminum and nailed in place. It would be then caulked were appropriate. This would be a treatment that would then be maintainence free.
You won't know if you can do something if you don't try.
