Spar Varnish

Here is Sandy varnishing the masts in 2012.  We filled the checks, or should I say, re-filled the checks with pine pitch.  Great material.  Melt it, tape off the check, pour it, or pay it in with a putty knife, scrape or cut flush with a chisel edge when the pitch has cooled /cold  (about15 seconds) and  you can varnish over it right away. The mast was last pitched before we owned the boat, so at least 25 years ago.  Keeps the water out and varnish really sticks to it.
