Thanks for the input and suggestions. My neighbor put a composite step on his to avoid all that work of applying oil, cleaning etc. My boat cover goes over the step now which I find a lot easier. Just to clarify from my previous posts - $100 is for the snap cover for the boat. I only wanted $35 (including shipping) for the swim step cover which, to me, seems cheap compared to the cost of the oil, chemicals and labor - sort of like the proverbial "ounce of prevention" rather than doing a lot of work to make it nice again. I'm open to offers if you think that price is too high on either cover.
