We know better, but a lot of people have too much faith in this type product IMO...
What's bad about all these claims from manufacturers is the false sense of security it can give to people, mostly the average Joe that dosen't know ( or seem to care enough to research it ) about the things we discuss here.
Case in point; I was called by someone with a 1997 Sedan DeVille, and they wanted it washed. I washed it, and found some bird dropping etchings in the clear. I mentioned it later and explained what caused it and why...my customer looked at them illicited a quizzicle face and then comments about the car having a dealer supplied"lifetime sealant" followed, and that he always left the bird droppings on it because of that, and didn't worry. He was pretty steamed and was going to call the dealer. I tried to tell him the deal with things like this, and that there are no panaceas against the world's abusive biological and man made nasties, but he still felt like someone had swindled him out of his life savings. LOL.
I don't know what the fine print is on these dealer supplied "sealants", but i'm willing to bet it dosen't cover total neglect. You think?
He traded the car in shortly after, and I spoke to his wife about it once shortly after that, but she said the dealer wouldn't repaint the hood, and she left it at that. He bought a Lincoln too.
I wish I were a fly on the wall of that dealership when the topic of "dealer supplied paint sealant" came up in the buying process.
