[C320-list] Catalina 320; interior varnish refinish

[mmellon at cruzio.com]

Hi, Graeme. Thank you for the detailed reply.  I took the teak trim
piece off, and discovered the back side was also varnished but was much
darker than the front (normally exposed) side of the piece.  I am
assuming this may be due to sun bleaching over 22 years of daily
exposure through the portlights and hatches.  But your comments have
caused me to reconsider.  So I bought a can of ZAR water-based clear
satin varnish - but got the same darker result when I applied it to the
sanded teak. 

Did you use the Target water-based varnish or something else such as I
did? 

Thanks.
