Sigh. Same here. Mine only touches about half the time so whatever. It only scrapes a little when the lid/deck/tonneau cover rises to store the top. When I put the top up I have no issues. So I'll just let it scrape.

see the new thread. nissan engineers have come up with a new bungee to fix the fifth bow issue - lid rubbing the roof. It just came out this August (2019).
