While waiting for My 2010 Escape to be built, I've been left with the option to have the Rust/Sound proofing sprayed on the underside of the car at the dealership when it arrives. Is it worth it? There's also an Electronic, enviro-friendly version of the rustproofing that is apparently transferrable when you decide to trade your car in. Cost is $699.00 Canadian for either. Can prob get it for $499.00 according to Finance Manager. Just not sure on my plan of action. Cheers.
