Well if you want to pay for something like that that's fine but your paying for something that is really kind of a paint sealant type material.
There are better products on the market and this is so over priced and "Hyped" Tell your buddy to save his money and if he wants his truck to be protected then look around as there are several products that can be purchased for less and applied.
Just a thought, Ziebart is very over priced in many of what it installs, Dealers offer these services also but beware . . . . . . . . it is really a negotiating priced item they do to get you to buy the car as it is nothing more than a paint sealant and they offer leather and other kinds of gimmicks to make money and I feel that they offer really no protection as something you could do or use at home.
This was a big practice in the 70's, 80's & 90's but with bc/cc paint they are not offered as much as they were before.
Again it is his money and if it makes him happy then be so . . . . Good Luck . . . . .
