I was a Zaino fanatic! All my cars had like 30 layers, my vocabulary was full of phrases like, "optically perfect" and "diminishing abrasives". My towels were all 100% cotton, Cannon and fieldcrest WHITE towels (colored towels could transfer dye) and I would of punched you in the face for recommending any other product, lol that went on for like 8 years! I'd always try other products to try and evolve, but I stuck with Zaino for the bulk of my work. It really wasn't until I joined Here, that I really came to learn true paint care and how different products give better results for different paints, paint colors, etc. (thanks AG!) Now, I refuse to be fully faithful to one manufacturer, the products are evolving so fast, it's amazing!
