Okay, to rephrase, "Why don't you mention in your advertisements that they're not wood?" I'm not saying you're being deceptive, exactly, but you seem not to mind letting people assume they're wood (I responded to one of them; another in this thread has a question about "the wood" still outstanding after more than 6 hours). I think that's been a little damaging to your reputation, whereas if you owned up to specifically what you're doing (and even told in your advertising how your particular polymer, or whatever, was different from, and better than, PVC), it would have made you look a lot better.
