I have used Zaino since '02 after reading reports of it's durability, and also based on pictures I saw of Zaino'd cars.
I've tried everything, but this stuff ain't working for me. One good rainstorm, and it's about gone. Dust and roadfilm eat right through it also.
This stuff has not lived up to the hype.
I first tried it on my Formula that does not sit in the weather, and is not driven in the rain. It looked great, but the few times it got rained on or driven in the rain the Z didn't hold.
I tried it on our '90 Sunbird next, which was my wife's car at the time. It barely lasted past the first rainstorm. I chalked some it up to the paint being old, but I was still disappointed.
We bought a 2000 GTP last July, and I went for the Zaino after about a month. I did 3 coats of ZFX/Z5, then another 2 coats a week or so later, and it worked great. 3 weeks later I put another coat of Z5 on. I noticed the water didn't bead well before that coat, and it hasn't worked since.
I really thought I had the problem fixed. The last two coats have beaded water incredibly when I sprayed the car to wash it off. However, we had been in a long drought. Two weeks ago, it rained 7 inches over 4 or 5 days. I washed the car last weekend, and sure enough the rain had put a hurtin' on the indestructible Zaino. The beading had greatly diminished on the top, and the beading stopped where the roadfilm had slung up on the side of the car. It has rained tonight, and there are spots on the roof and trunk that aren't beading for spit. The Sunbird isn't beading at all. The GTP had a coat of Z5 3 weeks ago, and the Sunbird about 2 months or so ago. I've noticed the water doesn't bead good on my Firebird even after a coat either. If rains blows in on the back of my Formula, it cuts through the Z.
I've just about had it. I bought AIO with the intention of using it under Zaino. I hope this helps the situation! Elsewise, I'm done with the almighty Z. I use the Z6 and Z7 always, but nothing works. Even using ZFX doesn't make a difference.
On top of that, Sal Z. won't answer my emails or anyone else at Zaino.
Sorry for the rant, but this is getting old.
