I see you have a 2012 X23K, I assume you mean 23B or 23J. Which decals are you having issues with?
When I bought mine, they said there was a recall(???) on the front decals. Mine looked perfect, and asked if I wanted them changed out. I said no, and they gave me the stack of decals in case I ever needed them. They still look perfect. Actually all of my decals look perfect.
I wash (wash/wax solution) my HTT a couple times a year, that is it.
