Exterior trim PVC

I am attempting to replace the rotted wood trim on door and windows on the south side of my cedar house (NJ). I bought 4 inch PVC and rented a table saw. I believe I will have butts/no miters because I need to use 2" trim on certain verticals. Do I need to add flashing or other elements before I simply glue and nail the pieces?

No pictures so it's hard to say.
If your cutting the boards to length you really needed a mitre saw not a table saw.
I use stainless steel trim head screws not nails when installing vinyl trim.
Unless your doing angled butt joints there's no glue needed.

Some water/weather proof caulk wouldn't hurt.

Don't forget a drip cap above the doors and windows. My 1924 cedar house did not have any above the old doors/windows.

When replacing my windows, I trimmed them with Azek and bent up a cap for each to tuck up behind the siding.

Tried to attach 2 pix but they are too large. I'll try to zip again later. Wondering whether a replacement layer to repel moisture is needed before the PVC pieces go up. Oh, and I used the table saw to rip the length of 12' pvc.
Many thanks for your help.

azec can be gun nailed no problem.. screws arent the only way.. but stainless steel is. if you use standard galvanized finish nails they WILL bleed.. and you'll have streaks on the new trim within 6 months
