I spent all day cleaning my shop so I can finally start varnishing my Guillemot ES. On an earlier kayak, I used masking tape at the sheer when I varnished the hull so I did not get varnish on the deck till It's turn. I repeated this process with every coat on hull as well as deck. My question is: How do you guys handle the varnish transition from hull to deck? Is there an easier way than my sheer taping method?

TIA,
