Putting more varnish over old?
I have a dining table from the 1960s that is in pretty good shape with just a few minor blemishes on the top. I'd like to add a coat or two of varnish on the top to even out the flaws and protect it better for daily use.
Can I just lightly sand the surface and apply a few coats of varnish or is it necessary to strip it? I'm worried that the little dings might look bigger instead of getting filled in and leveled out if I don't strip it. But I don't want to alter the color of it. (And of course I don't want to do the extra work.)
