I'm looking for a vinyl siding that overlaps end-to-end. One product catches my eye because it's got a nice multi-tone wood-look: Gentek. The problem is that the nice vertical appearance getis broken by a horizontal piece of trim that has to run where the siding pieces overlap. Kinda spoils the whole vertical effect. Does anyone know of a product that is vertical, vinyl, and where the pieces overlap like horizontal? We get a lot of rain and so it needs to be reliably weather-resistant. Suggestions welcome!
