I want to put an extra reinforcement on the keel of my kayak of fiberglass and epoxy.
is it nessesary to take off the varnish coat first or can I just sand and aply on top of the varnish?
Yep, there's some sanding in your future. As a general rule two part systems go on before one part systems. If you don't mind my asking why are you needing reinforcement?

Hi Bob, thanks for the reply, the sandy beaches here at the costa brava seem to like varnish , I noticed the 5 layer coat I put on is already gone on some parts of the keel. ( 8 times going out)
I was thinking of putting on a carbon fiber strip with an epoxy carbon powder mix.
maybe I will just have to use a better varnish, two component?
CLC sells a handy kit for this. I scraped my Merganser down to the glass on a concrete ramp. I applied the CLC kit and have seen no damage after three years of hard use. Photos and description at http://twofootartist.com/merganser-construction-notes/ Scroll to July 2010 entries. -Wes
