I posted Turtle's headlight restoration in December of 2014 in this thread, and the Blue Magic lasted a little over a year. It was starting to haze lately, so my son brought Turtle over and we re-applied Blue Magic restorer and Blue Magic sealer.
I applied it with my cone buffer again, and it literally took only about five minutes to do both headlights. A year in the scorching Florida sun isn't bad for a five minute job!
