work in British Columbia Canada, Sales....the business office sell a 4 seperate packages or you get it as one...we call it a chem pack...basically it is undercoat, guaranteed for life, checked every 24 mths for wear, next is a paint protection which I used and have to say after 19 mths water still beads off my car and never touched the paint except to wash, the interior is a scotch guard for lack of a better word, basically it protects from stains, tears, wear, holes in leather, I got htis to as I have kids, my brother did get his seats replaced in his Colorado with this as he got stains from working at hte mill and could not get removed, so they replace the seats....that is what your looking for...also a rust protection which is an electric modual that only allows negative charged ions ( sounds stupid I know but it works) to any part on your truck that is grounded...bassically everything......it is pricey here about 1800 bucks for the package (here anyhow) however look at it this way you are not paying for the product necessarily you are paying for the coverage and waranty it gives you

may be different in the Us I dont know also sometimes if we are booked solid Toyota donw the street does the same thing and we will contract out to them ot have vehicles done....if you cant find a GM dealer to do it check other dealers. look closely at it some are no good, check the guarantee expecially, the one here is awsome guarantee....that is what you are paying for, anyone can put undercoat on....get them to guarantee it for as long as you have the truck from chipping and flaking.....no one will..

 

Oh I see, you work for a dealership in sales not actually for General Motors.
