I just added a pre-hung exterior door to the side wall of an attached
garage. The house has blue aluminum siding and the door and trim are white.
My question is what type of caulk should I use for the spaces around the
exterior frame where the aluminum siding goes in under the door trim.
My guess is to use 100% silicone although the tubes say silicone is not
paintable. As far as color, I am assuming either blue (if it comes in that
color) or clear -- because I think that will result in the white trim being
a straight edge and that will look better suing white caulk and having a
jagged white edge around the door.
