Spray Ceramic Coat frame and underneath?

[Macallan]

Now that we have spray ceramic coatings relatively cheap, anyone spray the bottom of their vehicle? I'm wondering if that would be better than fluid film type stuff... I thinking of spraying it and leaving it (and not buffing it off since its the underneath)

Something like this,$30-$40:

Graphene Ceramic Spray Coating™ Advanced - Adam's Polishes

Ceramic coatings don't have any corrosion inhibitors. Total waste of money.

These frames seem to rust from the inside out so unless you fill the inside with something that stops the rust I don't see that it's worth the effort. These frames like to hold debris in certain spots, add salt and moisture and you get corrosion.
