1×6 pvc trim with a 10 degree bevel on top, 1×2 drip cap with a 10 degree bevel on the backside that meets the housewrap/sheathing.  should these be glued together first, then installed as a single peice?  never worked with pvc before… the long lengths are gonna make a nice appearance but not sure if I can join these 20 footers with the drip cap beforehand.  maybe glue in place is a better option with the watertable firmly attached to the house?

thanks
