It sounds like you might be missing some when you go take it off, or maybe you aren't letting it dry fully before removing it.

Can you give me a list of the exact, specific products you're using? Meguiar's makes several different carnauba waxes, polishes, etc so knowing precisely what you're using and how you're using them is important.

Also, keep in mind that you should be applying a very, very thin coat of wax to all the painted surfaces of the vehicle and then let it dry fully before removing it. You can even leave it on for several hours and it will remove effortlessly, provided you applied it thin to begin with. This thin application is where most people go wrong. I've had people tell me they like the size of the Gold Class liquid wax bottle because they can wax their car twice with it. In reality, you should be able to wax your car 10 times with a single bottle of the stuff. You should be putting your wax on so thin that it's almost hard to see it.
