Hello There, Some of the Paint Protection Systems are very good but unfortunately for most motor dealers, these schemes are about profit not protection. The prep work carried out beforehand is paramount. Valeting staff in many dealerships are just not up to the job. They are not experienced / skilled enough, to be using machine polishers, nor do they know the best application methods (to avoid swirls / micro-marring etc). Add low quality wash mitts, poor washing techniques, cheap microfibre, time constraints etc to the mix and you get poor overall results. If done properly however by a craftsman / pro detailer, Full Strength Sealants like A-Glaze Plus, AutoGlym LifeShine etc. will deliver long term protection. They will protect for many years unlike off the shelf products, it's just that they are not ultra low maintenance solutions, as dealer packages always seem to suggest.
