Undercoating a car is a bad idea. It will eventually separate and then is traps water and salt between the undercoating and the car. Keeping the car clean, waxed and undercarriage washed off is a far better rust stopper than undercoating. I did try using the applied oil bath rust protectant "Rustcheck" applied by T and T Auto on 145St and 118 Ave. It is about $130 a year to apply it and if you are going to keep a vehicle for 10 or more years, it is worth doing. If you sell them more often, not so much.
As far as protective film, the best place I have found is Proform Auto Tint 3127-92 St Edm. Gerald did the last install and did an immaculate job, including Clay Barring the whole area before applying the film. They use a product called Premium Shield. It stands up far better than 3M and it does not yellow with age like the 3M does. He was about 40% cheaper than most of the other places I checked and WAY cheaper than the dealer.
