Hello all,
I am installing 3 new exterior doors with a doug fir veneer. All are exterior doors but 2 are covered by a breezeway connecting the back door to the shop, and the 3rd is between the shop and garage so it is technically an interior door but neither shop nor garage are heated nor conditioned.
I understand that spar varnish is considered exterior and is softer, but this is California along the coast with the lowest temperatures in the 30's and the highest in the upper 80's and sometimes maybe mid 90's but darn few of those.
Since there is no direct sun exposure and unlikely any rain on the doors, would i be better using a non spar, but oil based, varnish . . .which i understand is generally harder and easier to refresh??
Similar question with the next project : the front door with an extended porch such that only bottom would ever get wet and then only with blowing rain, and minimal direct sun only early on summer mornings?
Again, thank you for your willingness to share your experience and wisdom, Patrick
