I found a little info. It looks like a dealer applied thing similar to the diamond gloss or what ever it's called at zybart stating no waxing etc. I don't buy into it and expect that they will say you must come in every 6 or 12 months for a reapply for warranty...who knows that cost.
Here is a web site with a little info

It appears to me it more paint protection than rust proofing he bare parts...IMO tell the no thanks on this but I imagine it's just some glorified wax job.
