Nice winter project.
Here's a suggestion for you that might make a nice winter project.Take the handrails and other parts off the boat. Take them home to a nice warm shop and, using them for templates, cut out NEW pieces– out of MAHOGHANY!!! Think of the advantages– that beautiful rich red colour, much better weatherproof properties, and a farewell to that awful oily teak that goes black, white, grey, brown, whatever.The secret to ALL exterior woodwork, even when there is not a lot of it, is WEST-system saturation epoxy. Thin some out with acetone and 'paint' it over the piece (on some paper, on the floor or driveway– don't get it on you. Use a mask). Do it again. Then sand it lightly. Using something really good like ZSpar Captain's Varnish (it must have a UV-inhibitor) give it at least three good coats, sanding between them, before reinstalling on the boat. Use a very good bedding compound and all-stainless fasteners. It will stay nice with just wax or Star-Brite for years.Even if you elect to keep the teak, finishing it with epoxy and varnish will work wonders for looks and endurance in the elements. How do you think all that brightwork on a Cherubini 44 gets to look and stay that way? (except we'd varnish about 9 coats, not merely 3!)JC
