50 layers... wow. Wish I had the time!
If you don't find a detailer who does Zaino, give it a shot yourself. It's quite easy. After washing and claying your car (if money is a big issue, there are cheaper options for wash and clay available OTC), apply a polish (Zaino AIO is great) and then either Z2pro (i like for metallic paint and lighter colors) or Z5pro (a little more depth/warmer). Beyond that, just washing will maintain the longevity for months. As you continue, you'll likely add to your arsenal. The Z7 Car wash is amazing as is the Z6 detailing spray and the Z8 Grand Finale Spray. For my money, I've yet to find a slicker combo than z5pro or z2pro and z8. Water doesn't stand a chance on the paint.
Best of luck and happy detailing.
