Undercarriage Treatment/Protectant?

[azenthusiast]

I have been asked to do a full detail on a car next weekend and after asking what I did, they mentioned that another detailer had used some sort of treatment on the undercarriage of the vehicle and they would like something similar done. What is the best process to use on the undercarriage beyond the typical wash?

Think it's just this they're talking about?

That stuff is very good.

Thanks guys. That looks to be exactly what I'm looking for. In the past, I have not focused much on undercarriage protection here beyond a typical spray since winter is basically non-existent, but I want to cover all of my bases to give the best detail possible for this vehicle as I am looking to get to the next level with my work.
