Hello together, I would like to inquire about your experience. I am currently using the Maguiars product range, it was rather a coincidence that I came to this. For hand washing the Gold Class Shampoo about 50-75ml on 12 liters of lukewarm water. Drying with the Water Magnet, details with the yellow microfibre cloths. Every about 6-8 weeks the Gold Class Carnuba Plus and after every second car wash sprayed the Quick Detailer and rubbed with the yellow microfibre cloth. So far, so good. I feel the products to be processed well, fragrant and (apart from shampoo) economical in use. What bothers me is the low service life of the products. The Carnuba wax lasts 3 weeks, if at all, then the bead effect and the “cat flies on the ass” effect is largely gone. The Quik detailer, I use both with and without Carnuba, hold one, maybe 2 days, then the effect is also largely gone. My questions to the professionals: ste If not, what do I do wrong? Are there products in the normal price range that have a noticeably better service life, how is it with the Collinite 476S, for example? Or do I make a fundamental mistake, e.g. too much to expect in car maintenance? Thanks for your feedback, Px.
