Rust proofing a new rear arch/wing?

[Meds]

Hi guys.
I'm halfway through the rear arch swap, everything removed and i plan to install the new arch tmrw.
It suddenly dawned on me that I should ideally treat the inside of the new arch with something such as Wax/oil?

Any recommendations?
The wing has been fully painted and lacquered in the inside.

Thanks.

POR-15 is what you need

I'll check them..
What particular product are we thinking? I dont need to prepare/convert or treat an existing panel as it's brand new and just painted.. I'm thinking of a wax type solution that seals for the future.

Paint the inner lips and under the plastic brackets.
Also very good to do wheel arches under the plastic liners.

I've picked up some Tetroseal underbody sealant that I hope will perform the same function.
I hope.

Personally I always use clear Waxoyl in the arches behind the liners and inject spray cavities. Soak the container in hot water to thin it down for good results using the spray gun.
