Underbody Protection Spray Places in Socal?

I am moving to North Dakota for college this fall and I want to protect my truck and the underbody from all the corrosive elements I'm assuming will be there during the winters. Anyone have a good recommendation for shops that undercoat for a solid price in Socal area, specially San Diego? Also, is this really needed in the first place? I want this truck to last a long time I got a 2020 TRD OR MT.

 

Do not 'undercoat' in the traditional rubberized product sense.

Search here for products like Cosmoline, Wool Wax, etc etc. Most of these are available as DIY items.

And yes, you should do it. You'll likely regret it if you don't.
