Zaino = Miracles; a disbeliever\'s story. Well I finally tried the Zaino products I bought & had sitting around. The other day I showed my wife how our '99 BMW 540i Sport (black) had scratches all over the hood, it looked like the car had dust on it & someone put down heavy paper grocery bags and slid them off of the hood - or like someone sat on the dirty hood. It looked bad - I showed my wife to set her up for a pro fix-up. Well, I thought nothing to lose I'll try that Zaino stuff everyone says is so great. I followed Sal's instructions precisely for fixing scratches with Z5 & Z2 etc., blah blah, figured no way would this work. Thought it was a waste of time, but why not try the stuff before I put it on my beloved snake. Well, after 3 applications I showed the car to my wife in the bright sun, she asked when I took the car in & how much was the paint work. Scratches were undetectable, I literally can not believe how the car turned out, it looks better than brand new. I've never had a finish look this good - and that's with a black finish that started with lots of fine scratches. Anyway, I'm a believer now, sorry for doubting you Zaino Bros. & you folks that professed it to be great, your stuff is truly unbelievable. You've got me for life. The snake is next!! Dave.
