yeah four years easy.

You should only polish your car a few times a year, maybe with each season change. For each panel you should be using very little product. Maybe a nickel size. If you use too much product you will get the hologram or cloudy finish.
The PC videos link in my signature shows this common error.

The spray waxes and quick detailing sprays should last a couple of years at least. Those you should only use immediately after washes, if you use a rinseless wash then a little more frequently. The paste wax goes on monthly for a daily driver so that's another two years worth at least. Some people go overboard and wax every weekend..very bad for the paint.. too much touching.

with your color car its pretty hard for any wax not to do a good job. Even the turtle wax ice stuff at Pep Boys would do an A+ job....just won't last very long if you wash allot.
