Best Glass guy around on this coast is Kevin Horn at american boatworks in Tarpon. They do incredible work, and he standsa behind it. He did my transom, and several others I know of.
Pretty wild link showing some of his work. Tell him you know me from the website. The cool thing is he will make a cd of the repair of each of the steps at no charge if you want.
