I don't want to varnish, but I would like to "enhance" the look of the older wood in the interior of my boat. Frankly I think I am looking for furniture polish, but I'd like to think there is something a bit stronger and longer lasting.

I am basically looking to wipe down the interior and bring up the appearance of the wood, but I don't want to go to the slick varnish look.

Any ideas, suggestions? Linseed oil?

Thanks
