No big problem having a non-clearcoated finish. The DACP is a very good cleaner and polish for defects and swirls that are all over. Some people get a little haze after DACP, but this can be removed to a high polish with 3M PIII-MG and or Megs #3 or other products as well.
Here is a good link to Zaino tips/tricks:
Nick's Unsolicited Tips and Tricks
Once your done getting all swirls and defects out (remember Zaino bring out or highlights these things as it's very clear) wash all oils off the finish with Dawn followed by Z7 wash. Dry and you're ready for ZFX/Z5! This makes the finish ready for Zaino to bond correctly. Remember that Zaino is to be applied THIN. Think of the bottle costing $1000.00! If you do get streaking with the new Z5, I mixed up a batch of Z7 and water in a spray bottle (used mostly as clay lube) 12oz water, 1/2 cap Z7. Spray the streaked area and wipe off with your MF towel. DO NOT RUB HARD! Apply more spray (Z7/H2O) and wipe again. You don't want to add more micro-marring by wiping too hard.
The PC is very forgiving and as you learn, you'll understand it more on how it reacts with different cleaner/polishes with pads.
The best thing you could do after reading all the stuff here, post a picture of the finish in this thread so some of the members can also evaluate and comment and recommend what to use.
Just make sure you schedule enough time to do this, as I've seen too many people who are new at it get frustrated and rush it so they can go elsewhere. Take your time, enjoy your results as you go along. If you have access to a garage and can get a halogen work light that will assist you in checking your work as the light is VERY unforgiving and shows all. This way B4 you start, take the light on the area and look at it. Next, start your polishing, check again with the light. See the swirls diminishing? Great, next area. Don't try to do a large area at once as well. Start small/stay small. Another pitfall on new users of the PC, they try to remove defects on say a whole hood at once. Look at the mfg sites as well, Meguiars, 3M, Clearkote, Poorboysworld, etc to get an idea on what these things do.
Enjoy the new way to deplete more money from your wallet! But results are well worth it.
