Dealership is offering a clear coat for 450buck. anyone??

[Ma\'Deuce]

The dealer says they have a clearcoat for the exterior to save paint fading. an undercoat for rustproof and sound deadning and an interior coat for fabric protection and trim fading. all this for about 450bucks. and when you trade your vehicle in they give you 200bucks of it back. anyone else get this info from their dealer and did you do it? is it just a dealer moneymaker scam? I'm more inclined to have the underside Rhino'd or Linex'd than anything else. what do ya'll think?? thanks for the conversation and or tips.
