I've got another newb question.
I'm installing Azek trim around around Andersen 400 new construction windows. I have the Azek historical window sill (AZM 6930). It has a 13 degree bevel over the entire top of the sill. This bevel leaves a gap under the front lip of the window. I can still seal the back part of the window but should I flatten (trim off) the part of the sill that will sit under the window so that I can seal the front edge of the window. I hope this makes sense.
I tear things down and build them up.

If you'd like it to be tighter to the window, then yes... take a 13 degree cut off the high part of the sill that meets up with the window- just enough to make it flat where it touches the window so that the flat part will be hidden under the window. I run a bead of white Vulkum against the window, then push the Azek up into the sealant. None should gush out if you keep it back there a ways. You just don't want water running back behind your trim there. It saves you from running an ugly bead of caulk on the surface.
Thanks, that's what I thought. I didn't know if there was some reason to keep the angle the same even in the unexposed areas. Drainage maybe, but the water has to be sealed out before it gets that far anyway.
