Right now
I am shutting this 'puter down and heading for the boat.

I think Oil sounds the best after reading all the posts. I have almost
finished sanding and the grain is beautiful. I would like it to show
and certainly don't want to hide it with orange paint. Varnish is a
close second as I think it can look great but probably wouldn't be as
good on a swim platform as on a hand rail. I am worried that the oil
will discolor but it sounds like it will be easier to clean and redo
than varnish.

I am at least grateful that I can refinish the teak. I also have a
Mirage that has a gel coat swim platform and it already looks brown
discolored and dull after only a few years and I gather there is very
little I can do about this (short of painting it orange).
