The Terrace is so much better than a Sunbrite, you would be doing your client a disservice to not use that.

I don't know where you're located, but here in Portland I had a takeover job where the original installer put a Playbar outside on a mantle in a covered outdoor living space- the homeowner was on their third one in 4 years when I walked the site. Can you post a picture of the install location?
