QD doesn't really do much for it. I'd say that
Souveran will last you a good 6 weeks or longer depending on the conditions. I would definatly reapply it every 2 months. I put on one coat per month usually. It works pretty well. I put a coat on my wife's car 2 months after the last treatment and you could still tell that the carnuba glow was still hanging on a little.
Souveran is a wax for people that don't mind spending an hour every other month or so on their cars. You'll love it!
