My wife and I had to leave our cars outside of the garage for about 5 days. Both cars got hit with sprinklers daily, and the water dried on the cars, leaving heavy water spots / mineral deposits.
My wife's car is a 1994 black Infiniti G20. I had 5 coats of Z5 and 2 coats of Z2, the last coat of Z2 was put on about 2 weeks before the car was left out.
My car is a smoke silver "E320" and had one coat of Meguiar's #20 Polymer Sealant. The coat of Meguiar's #20 was put on the same day as the Z2 was applied to the Infiniti G20.
I washed and detailed both cars this weekend.
The results?
The water deposits chemically etched the paint on the G20. Went right through the 7 coats of Zaino, and left mineral deposits on the paint. I tried my Dual Action Polisher, and it wouldn't remove the chemical etching, even with Meguiar's Compounding pad and #83.
I had to pull out the DeWalt Rotary Buffer and use the Meguiar's Compounding Pad and #83. I then stepped down to #82 and the Polishing Pad, then #82 again with the finishing pad. I then hand applied Show Car Glaze, and just applied a coat of #20 Polymer Sealant.
My E320, on the other hand, remained completely protected with one coat of Polymer Sealant. Everything just hosed right off, and the paint was spotless. All of the water spots, bird droppings, dirt, etc. just hosed right off.
I'm done with Zaino.
I got a bottle of Z5 and a bottle of Z2 for sale. Unopened in original condition. $5 for each bottle.
