I have been a forum member for only 2 weeks, but in that time I have been convinced to try something new. About 6 weeks ago, I ordered over $300 worth of stuff from Griots Garage (Yes, I feel for ALL the hype they had printed in the catalog) and I am NOT impressed not happy with it at ALL....and that was before I became a forum member. I just called and got authorization to return all the stuff (except for the MF towels and PC bonnets). I will have a huge refund coming to me (I do like the thing they call Speed Shine) and I am going to spend it on......ta da......Zaino. So once the dust had settled, and I get the new stuff, even though I have read countless times how to use this stuff, I will be here asking for a refresher. After my refund, I will also explain which PC pads I have to make sure I have the correct ones (some from Meguiars and a couple from Griots) and if I don't, then once again I will follow the advice expounded here. My '78 is black and so is my (new to me) 2000 vert. I can tell that one of the previous owners must have run it through a car wash hundreds of times. In fluorescent light you can see MANY little scratches, so I hope the PC Fusion will take most of them out. The 2000 is my daily driver and the '78 is a show car (which I drive to the shows). I will keep you all posted.

Very simple to understand:

Wash
Claybar to remove embedded contaminants
Wash
Polish as necessary with abrasive and/or cleaner to remove swirls, scratches, oxidation, etc.
Apply Z2 Pro or Z5 w/ ZFX
Finish off with Z6 or Z8 if desired

That's the exact same process that should be used with any product line out there.

 

I tried the Zaino Fusion last week on my black Vette...using a foam applicator. Actually, polished the car 2x with it. In the end, I was satisfied...Fusion removed about 80% of the scratches. I am now in the process of applying the multiple Z5 coats.
Whether I could have achieved even better results with the Porter Cable and a different brand of polish...I do wonder.
There are plenty of knowledgable people on this forum (some professional detailers), who could probably offer some other suggestions to achieve your goal

 

I just put on my first coat of Zaino last night (will post a full critique later) and must say, I don't think you will want to use the PC with it. It really does just wipe off. Besides, the motion that they suggest does not lend itself to PC use.

Be sure to let us know of your results!
