Complete with the Aussie sense of humor. Love it!

I'm going to be actively pursuing an undercarriage coating solution, when the Spring arrives.

The kit for both the hand held and the rolling piece, along with the chemicals is $300 USD. Not bad, if it really works. Of course, it assumes that you own a pressure washer.

My cheap@$$ idea is a large coroplast sheet (plastic version of cardboard) attached underside by cleverly placed screws using beer bottle caps as washers.
However, oil & ATF changes take a few min longer. Want to keep my coroplast sheet, but also supplement using American versions of Aussie products.

Freely admit it's about as redneck an idea as I've ever had in NYC - an exterior mod that only my mechanics usually notice -
but for $25 it keeps my Z71's belly much cleaner than if I'd never done it. I laugh at it too, for what that's worth.

Do you have pics of your sheet in place?

Pics of my Tahoe'd get me banned - can't presently afford the money or the time to improve its aesthetic appeal.
It blends into NYC well enough that you might not be able to tell it apart from another black GMT821-Z71 quickly ...
unless you look under it. It covers the NZZ, and has cutouts to allow front tires to articulate.
Prevents snow & slush from sneaking in surprisingly well, rain too.
