Over 30 years ago we sided our colonial home with white, smooth, 4 over 4 aluminum siding. Over the years we have been very pleased with it. However, currently, we need to replace some siding, "here and there" on our home.We are having a very difficult time finding white, smooth, 4 over 4 aluminum siding. Does anyone know of a source/manufacturer where we could purchase some of this siding.It seems some manufacturer out there still makes it.:confused: We only need a small amount of it.
