I am ready to varnish my CH17.  I have a can on epiphanes clear gloss varnish.   I was reading the can and it give instructions for applying to bare wood.  I am applying to sanded epoxy so I figure that the finishing will not be the same.  It tells you to thin the varnish 50% for first coat, 25% for second. 15% for third and 0-5% for subsiquent coats.  I am thinking since the kayak is already coated in epoxy that I would  be OK with nto thinning the varnish at all.  This is my first time using varnish and I want to see if I should thin it or not.  Of all the reading that I have done, I have not read anything about thinning varnish. However, I may have read at one point that I should read the instructions for the varnish manufacturer and follow those.  Any feedback would be appreciated. 

P.S. I cleaned the gargage and prepped to varnish by vacuming all the dust and then I read the instructions on the Epiphanes can. I did not expect this to be a delay.  I hope to be in the water soon!
