I love the look of Epifanes Wood Finish on the interior
. It is not a really high gloss like some varnishes, and it is 100% more durable. It says gloss, but it is more of a semi-gloss. I use Penetrol to thin it, if necessary, and it usually takes longer to dry than regular varnish
under normal conditions. If you can afford to wait a bit I would just do that and keep the heat on. I usually put on the first coat pretty thin (using Penetrol) and then recoat every 24 hours for a couple of days, with only a very light sanding
inbetween. Theoretically, you don't have to sand between coats of Wood Finish, but it does improve the finish.
