So 70 percent of the handrails look o.k. I have a section that the varnish or urethane is peeling off on. Just for kicks I brushed on some Teak oil. The sections were the urethane had peeled off and the wood was white turned basically black. I know teak oil is not the solution, but why would it turn black?

Also, I know on the area were it is badly peeled I will need to sand and re-do, but is there a solution where there is just some spot peeling? can I sand that area and re-urethane it or will it just look like crap?

Also my bow pulpit is raw teak, and very dark grey in color. I put teak oil on it and got the same black appearance. How do you get a nice brownish orange out of that or is that not possible?

Thank you, and please pardon my ignorance, first time trying any of this!
