Trim at edge of cabin roof - Sun Cat

[dbybe]

Has anyone changed the wood trim to metal, that follows the cabin top where it breaks to a more vertical surface. Mine needs to be refinished but I do not look forward to all the taping. At first I thought it might be easier to refinish if I removed it, but it is a continuous piece so that might be difficult.

On a related note, any one try water based "varnish" rather that the traditional oil based?  I do not have a good place to varnish, out of the sun, that will have no dew in the 8 hours oil base varnish takes to become tack free.
