While I don't know the affect on the Advanced, it does slightly lower the longevity of the Spray Coating. However, if you only do it a couple of times a year, say before a car show and given that you have a true garage queen, it shouldn't be enough to require an early recoat. With the coatings, you can only use Brilliant Glaze on top of it since you have to apply the Coating on the clean paint surface that has been properly prepped or it will not stick.
