I am in the final stages of sanding the interior of my Northeaster and will soon (finally) be varnishing.  There are a few small spots where the epoxy coat was apparently thinner and I have sanded through to bare wood.

I plan to mask around those areas and roll on a thin layer of epoxy and resand.  Any advice? Will one coat do it or should I put two on to start with?

Thanks in advance for any advice.
