The only exterior wood that will be on my boat will be the trim on the sliding companionway hatch and possibly the handrails if I can find a suitable place to mount them. Since I'm running all lines aft to the cockpit, there wasn't room for handrails beside the pop top. May end up being mounting them on the pop top itself. As far as the rails go, yes I'm using the plastic ones from CD. I through bolted them, using a drill press with a fence to make uniform, proper angled holes. As is the case with with most everything else I do, I used too many fasteners, but oh well!
