I'm about to varnish kayak build #5. The first four were painted hull with varnished deck. This build, a Petrel, will be all varnish. I'll be varnishing the hull first, then the deck. I'm just wondering if there are any tricks to getting a good (invisible) blend at the sheer. I wouldn't think you would use tape like with a painted hull, but maybe that works OK. (?) I recall hearing of builders that somehow mount the boat to rotate, like a giant rotisserie, for the varnish application. That would be pretty cool -- a good way to avoid runs in particular -- but way more work than I'm willing to invest (even if I had any idea how to do it).
