True varnishes with a semi or satin gloss do not have uv filters and are only intended for interior use. There are some quasi-varnish wood finishes that come pretty close to what you want: Cetol Marine Light, Cetol Marine Teak and Epifanes Wood Finish Matte (over Epifanes Wood Finish Gloss). They are easier to apply than true varnish--no sanding between coats. Cetol also requires fewer coats but is not as durable as true varnish. However the maintenance isn't too bad--just scuff with a scrub pad and apply one topcoat once a year. I do not have personal experience with the Epifanes products but they seem closer to true varnish in terms of number of coats, durability and maintenance. You might even be able to use the Epifanes Matte over true varnish--check with Epifanes on that. ----- Original Message ----- From: "AM Middleriverstudio" <middleriverstudio@gmail.com> To: "montgomery boats" <montgomery_boats@mailman.xmission.com> Sent: Tuesday, June 7, 2016 5:30:23 PM Subject: Re: M_Boats: montgomery_boats Digest, Vol 160, Issue 5 For those that are fans of spar varnish, I have a question: I'm refinishing/repairing our hatch boards. They were already varnished so I decided to continue in the same fashion. What I have not been able to get is a 'semi-gloss' finish. i.e. the varnish is indeed, a super-high-gloss finish and unfortunately I'm not interested in the glare on a sunny day, nor in the way that it magnifies every flaw in the substrate. Is there any way to tone it down? thx a
