Have you used or worked with the signature series and feeling about them?
What is the main difference between vinyl and aluminum? i.e. Aspire and signature from Weather shield and Anderson 400 series and Architectural? is their any performance difference or just that aluminum vs Vinyl?
How is the fade rate with Vinyl vs Aluminum. we are going with a darker color Teratone and my understanding it I think Weather Shield may have had a problem with this fading quickly?
