   A ploughed trim refers to a board set on angle and ploughed to create a cove or groove on a table saw.

   Some of the facia boards I installed have a 1/2"x 1/2" slot cut in the face of the board, about 3/4" up from the bottom. Sort of a feature strip look to me. Looks nice, a little classier than a plain flat board.

   Most flat trikm that you buy, especially door and window casing, is ploughed back.  That means that the back side of the trim has a shallow dado running the length of the board.  If you have  a slightly out of plane condition, the two edges of the trim contact the sheetrock and door jamb, and the center rises clear of the obstruction.

   Mike ... I think you are installing that fascia board backwards.  The groove it there to accept the soffit panel.  You insert the soffit intro the groove, and nail the otherside up against the framing.

   And what is "sort of waterproof"?  MDF hates water.

   Don't know squat about ploughed miratec. Their web site mentions a ploughed fascia, but I couldn't find a picture. Gotta be a pre-finished groove for the soffit, but one size fits all?

   I have used miratek for fascia (not the ploughed stuff), it seems to hold up great. I've left some scraps out in the weather for over 7 months, and absolutely no dimensional changes. I think they've finally found a place for MDF<G> Don't worry, we can fix that later!

   We used "PrimeTrim" (LP, I believe) for fascia when we resided about 10 years ago, replacing some badly warped/split cedar. It's a sort of hardboard composite. So far it's held up quite well -- no visible deterioration.

   The stuff was supposed to be available with a soffit groove, but our local yard said they couldn't get that, so we plowed our own with a router.

   Prime trim is from GP. not LP

   Thanks.  I know what you mean about the door jam stuff.

   "Waterproof MDF" = Miratec (http://www.craftmasterdoordesigns.com/ and click on Miratec).
