So my name is John and I just purchased a new RV that I will pick up in a few weeks. So my question to everyone is they are trying to sell me a interior and exterior protection application that they say lasts a lifetime but they guarantee it for only five years . So has anyone got this and if so is it worth it or is it just snake oil?  They want like a thousand dollars to apply it which seems like a lot to me. They says it’s only takes 15 minutes to do the entire process. Any feedback would be gratefully appreciated. 
Thank you.
