Forget Zaino, Follow thes steps for the perfect shine, never a haze. It will take you a few days and some time but it's worth it.
1) Wash car with Dawn to strip the car of any residual wax, etc.
2) Claybar the entire vehicle to remove all of the impurities left from the washing.
3) Break out the buffing compound and buff the car BY HAND to remove all of the scratches, you'll be surprised what will come off.
4) Next, hand glaze the entire car to fill in any scratches and restore the shine.
5) Finally, use "Liquid glass" to wax the car. I put 2 coats on the entire car and 4 on the nose so that bugs come off easy.
You may think this is overkill but to bring your car's luster back without trapping the elements and putting "swirl" marks in it, this is the only way to go. Zaino can't even come close to the luster, I think they're overrated..........
