CT underbody is mostly aluminum, isn't it? Not much to rust down there??

If you want to protect underbody, then get Terrestrial Armor Package.

I would just apply a layer of high temp clear coat. If you have a spray gun and put the truck in high service mode it can be done quickly.

Don’t bother. It isn’t needed. If you have salty winter roads, just spray the bottom off with a hose every now and then. That’s all you need. Lots of aluminum and stainless Steel in the structure make it the most corrosion resistant truck on the road right from the factory. I wrapped mine like a Batmobile and then put ppf over top of that. But that’s all.

My undercoat person won’t do my Cybertruck. He has never seen one.
What do you folks say?
He seems exceptionally bright for an undercoat person! Smart man. Cybertruck doesn't need an undercoat, just spray it off when the temperatures get above freezing.

Tesla can void warranty on any coating that traps moisture, if if ya start drilling holes as well.

Don't give me that right to repair act crap I often read. This is exactly what one is doing to modify any potential coatings that are provided by Tesla by doing them on own.
