I am preparing to varnish the rails thwart and deck of a newly

appearance of Ash, any advise on maintaining the white appearance of the
wood?





I used to use thinned clear epoxy as a sanding sealer, that kept the
color pretty well, you will get some discoloration with anything, but
that worked for me.
