It's important to remember that what works for some might not work for all. We're all different with particular likes and dislikes. What make detailing so enjoyable for me, is the experimental process. ( The journey's the thing ) I've been detailing my cars/trucks since the mid 80's and have used all sorts of waxes, polishes & sealants. ( and many combo's there of ) Like many "Autopians" I've come to really like the Klasse AIO & SG. Many people will tell you that the preps the key! Claying, Polishing,Sealing, Glazing and for some.....topping. For the past 2 1/2 years I've found that claying, P21s Paintwork cleanser, 1 coat of AIO, minimum 2 coats of SG keeps my vehicles looking great. From time to time I top the SG with a coat of P21S Wax. Some days I see a difference using a topper, some days I don't. Most days it doesn't matter to me because I just love using that P21S wax!! Before I was introduced to the Klasse twins on the Autopia site, I got great results using just the P21S cleanser & P21S wax combo. Take your time........Have fun............Experiment and enjoy the results!!!
