We paid as much for our cockpit enclosure as some people pay for a good used car. I know, ouch! But it was worth it. Of course the conditions in the tropics are brutal - sun, wind, salt spray, stray lines whipping around, etc.... To keep our "investment" for as long as we can, I treat the canvas once a year with 303 Fabric Guard. I am now going to up that to twice a year. Once at the start of the season, and once mid-way through. 303 isn't cheap but it works well. I generally buy a gallon here in Trinidad because it is much more expensive up island. I also treat the zippers twice a year on the same schedule. I use Zipper and Snap Lube on most of the zippers and snaps and Bee Knees Zipper Wax on those zippers that are prone to leaking - the front windshield zipper and the connector piece to bimini zipper. The wax helps keep the water from leaking through during heavy rains or driving waves.
