I'm finishing my coffee table and have been using a Sam Maloof finish which is
Tung oil, Linseed oil and Varnish. I noticed some scratches after applying the
first coat and sanded it with 300 grit paper and applied the second coat. It
appears to be lighter on the places I sanded and wondered if I should sand it
down and start over. I did sand through the finish on those spots.

I really like the Sam Maloof finish by the way.
