Great Job Mike. I really like how it turned out.
One word of warning. you not only created a working slider, but you also created a step. With the nice slick paint job, and a muddy wet boot, someone will surely step, pull slide, and maybe even hurt them self getting in. Traction tape works good, until it's gets muddy. A small piece of expanded metal tacked right on top of it will really help keep from you sliding off and stretching muscles you forgot you had.
