Just refinished wood grained fiberglass exterior door & would like to know if spar varnish or polyurethane should be used as the finishing coat. What brand is the “best”?

Use Spar Varnish… Min Wax makes a good product…
Use a spar varnish. My favorite is Man-o-War marine spar varnish. You can also use an exterior waterborne polyurethane.
