Thank you gentlemen.
It is not synthetic deck teak, but a synthetic teak toe rail - all round. Also synthetic teak trim around the companionway hatch. There is real teak on the cockpit benches. Go figure - 2 materials. I will allow benches to simply weather to gray because once I start with Cetol (clear), I will be forever a captive. Owner's manual says zilch about it. French, you know. Joe, I like what you are telling me about just relaxing. Best, Dusty
