I noticed the top of the guardrails over looking a dock have begun to peel. Mostly on top and only a few spots. I plan to refinish top and bottom rails and the balusters. Orbital sand all surfaces with 60 and 100 grit and feather the loose paint. My only concern is that the wood may be Teak which I believe has a high oil content? Is there a special primer to use? Or is a special paint (oil) needed? How do I keep the salt water from damaging the paint?


I would sand the rail down until all traces of your latex and primer are gone. Now prime it with oil based Kilz primer then apply oil based Rustoleum onto that. These are both commonly available in Canada, I'm not sure about US (or wherever you may live.)
