For drying my SC430, I use a CWB and a Pakshak WW towel. The CWB whips with water right off FAST and the WW just picks up remaining water.
Pakshak for MF towels. Final wipe/QD towels: Autopia "CBT" towel or DFTowels.
Remember, prep is the key with Zaino. Zaino is NOT really a polish, but just a sealant protectant.
Other products may contain petroleum "cleaners" in them, so be careful of this. They will remove any wax or sealant that you previously applied. Try to stay with one product at a time so you get the best results. Mixing some can have a bad effect.
Megs #9 SMR then Megs #7 is a good combo by hand. If swirls a a bit more, try the Megs Medallion Paint Cleaner, no real abrasives, but a chemical cleaner. Works well by hand.
If you have access to a PC, then 3M PIII-MG if swirls are few. Then follow with Megs #3 MG or stay with #7 for a real glaze. If swirls are heavy or many, use Megs DACP, then glaze with #7.
Which ever way, it's all in spending the time needed to get the finish as mirror looking as possible. Remember that waxes and sealants just "protect" what you did, so if it's not that clean or not mirror looking to begin with, the wax/sealant won't do squat except add some oils (if wax) that sit on the finish and if sealant,just covers what's there with no real added benefit except that the finish will not improve with washing as all the "stuff" is under the sealant.
Enjoy the Zaino! See my SC430 in my sig and in the member gallery. Good example of Zaino on a good finish, however, I still have some swirls that need to be removed, but never had enough time.
