Ok, first, take your applicator and spray some Z6 on it to dampen it.
Second, think of that bottle of Zaino costing $1000.00. Put a small amountt on the applicator and wipe back/forth on horizontal surface. On vertical, up/down.
It sould be hard to see as you apply it. If you get a line of product visible, it's too much, spread it around!
Once set up, try "finger test". Run a clean finger over the area that you think is dry. If it is, it wil show gloss, if not, it will show wet or haze. As you wipe it off and start to get any streaks, get a spray bottle, and add 1/2 capful of Z7 to 12oz of water. Mix and spray on area that may be streaked. Wipe that off. It now should be OK. If so, Z6 the area B4 second application.
You DID wash any oils off after polishing with Dawn or Z7 right? Polishes contain oils/silicone with maybe the exception of Menzerna and make Zaino not bond properly to the paint.
When in doubt about Zaino application? Wash with Dawn or Z7 B4. If Dawn washed, I'd wash one more time with Z7 to remove any and all film left by Dawn.
Remember, only 3 coats of ZFX Zaino per 24hr period. Don't forget Z6 B4 and after each application.
If you still cannot resolve, please call Sal Zaino in the AM, 8:30AM-11:30AM for any issues/questions.
