Since 3 coats is the max for 24 you might as well do 3 coats, If you have any left over give your wheels a few quick coats.
Here are the steps I follow, very similar to Sals.
1.Wash with dawn (blue)
2.Clay Yes even if new car. use capful of Z7 with 12 oz of water as lube for clay
2.Wash w/ Z7, dry car.
3.Mix 1 oz (Half of the mixing bottle) of Z2 or Z5 with ZFX.
4.Spray cotton applicator with a little Z6. Put small amount of Z2 on CA (cotton applicator) size of a dime and rub it into the CA.
5.Start applying it to surface. Put it on very thin! by the time you get done putting it on the entire car, the starting point will be dry.
6.Remove with 100% cotton (made in USA) towels. It comes off easy doesn't it.
7.Apply Z6 to car one section at a time and remove with another 100% cotton towel. Use very little of the Z6, it goes a long way.
Do steps 4,5,6 and 7 two more times.
3 coats of Z2 and or Z5 is the max per 24 hour period.
