Telegraphing cap nails

Berger Roof Shield udl is locally available and provides a longer exposure time than many underlayments. I want to use it. It requires cap nails for install. My concern is that the projecting cap nails will telegraph through the metal. Will be using tuff-rib/ag rib exposed fastener. Will 29 gauge show the cap nails? Will 26 gauge?

Cap nails are great for water penetration protection but they will print through if walk on the panel and one is tight. It is not a huge issue and a staple will hold the stuff down quite well if you want and are not planning long term exposure.
