 Honestly, it should be looked as such. There are different variations of undercoating that you can do, but an annual application really kind of is a good maintenance item to consider. There's no reason that it shouldn't be just factored in. It costs less than most people's car payments, so when you look at it that way, it's really adding a lot of value to the vehicle, and it's going to keep it on the road a lot longer. People do oil changes. They check for all of their fluids on the daily. They replace ball joints when those start going, so this should be considered just as that.
