I have just finished sanding and staining the interior of an exterior door. Should I use interior or exterior polyeurethane on it? I'd prefer to use the interior variety because I happen to have it, but I'm not sure if I should use that or the exterior version, presumably since this is an exterior door and even the inside of the door will be subject to more hot/cold swings than an interior door would. Other than that I can't think of any compelling reason to use the exterior variety.
