Spaced Inwale Varnish Input

I'm looking for any insight or tips folks may have for varnishing the many 1/2" openings associated with spaced inwales on the Peeler.  I've done a great deal of varnishing in the past, but I'm always looking for the coolective genius of others...brushes, techniques, etc

Thanks, Mike

   Sand with little blocks of wood wrapped in stick it paper,  a paint stir stick wrapped in paper works nice too, just wrap the bottom few inches, a dremel for any thickened epoxy white globs, use the smallest foam brush, it fits nicely in the spaces.  Run a drip strip of tape under the inwale.  I use rapid clear from Epifanes for the first 3-4 coats, you don't have to sand between coats, then finish with gloss one or two coats.  Then do it all again as needed after a few months in the sun and salt!
