I just purchased a cheap set of hardwood oars and they have a cheap finish on them. I am planing to add several coats of good varnish before the leathers are sewn on. My question is, they did'nt come with varnish on the grip area. Is there a reason for this? Or is it because they are cheap oars? I wanted to make my own oars but I found myself with a shortage of time. Thanks for any help.
