Years of UV exposure and aging always turn wood a darker shade. Either
use the colored polyurethane (MinWax polyshades) or just slap on the
usual finishes and wait a decade. Plant a bush to obscure the view if
it is too annoying. Urethanes seem to have no problems over old
varnish on my projects. The standard techniques, such as light sanding
are OK. Using stain as a matching method may not work very well. The

The only thing what will match the patina of 40 years of aging is another 40
years of aging. If you use stain, it will look like crap and never match
right. It may match today and look uneven in a few months as it starts to
