proper use of AIO and Men. FP

I just finish surface restoration on my 1985 Porsche 911 (platinum metalic clear coat) and am thinking about the process for the next time I detail it.

Clean - DACP (~6 abrasiveness)
Polish - Men. FP (~3)
Pre-Wax - AIO (cleaner/acrylic) one or two pass ?
Wax - paste by hand

Any comments on using FP prior to AIO ? Useful or waste ?

I don't plan any painting this time.

I do need the DACP again for a bit more leveling of paint. Used foam pad last time, wool pad OK for more aggressive cut ?

Rotary or R/O?
You probably are using a rotary since you are planning on leveling paint.
That's pretty hard to do with a R/O polisher.
A rotary and a wool pad will be very aggressive and can remove a lot of paint in a hurry. (Don't ask me how I know:() If you have the talent it should work great.
A R/O and a wool pad doesn't seem like a good combination to me. :dunno
Maybe just work the DACP longer. Even make several passes.
What little I have used DACP, I did need to follow up with a less abrasive polish. I used Meg's #9, but I have no idea where the Menzerna FP falls in the abrasive scale. Based on my limited experience, the AIO isn't going to do much with the haze left by the DACP, at least on GM paint. It would be a great cleaner/polish for a base for your wax/sealant.
Note: If you keep the 911 in the 80+ mph range, no one will notice the paint flaws.:)

Sorry R/O, not rotary. Not exprienced enough or trust myself with rotary.

I already did multi-pass DACP and worked in long time with foam pad (yes, it can get there eventually).

I was considering Meg. #4 Heavy Cut (~8) with R/O but I already have wool pad. (I did my two SUV's and they need more leveling so multi-pass not desirable.)
 
Meguiar's doesn't recommend the #4 for other than rotary use.
It probably needs the heat of the rotary to properly break down the abrasives. Just my opinion, but I would stay away from the #4.
You could try the wool pad on a panel to see the results, but what you are trying to do really sounds like a job for a rotary. Possibly even wet sanding will be needed.
If you are concerned about leveling orange peel, keep in mind that the orange peel may be in the base coat rather than the clear coat.

I'd stay away from Heavy Cut and wool pads. Too good of a car to risk that on :)

Menzerna IP just might work in place of or in addition to the DACP. If you're willing to incorporate yet another product may be give this a shot all via PC:

IP --you can try all the way up to "6" on the PC
FP--4 to 5 I'd try
AIO X2 --I don't see needing to go higher than 3

or maybe even, DACP
IP
FP
AIO X2
(same speeds)
If you try the later do a small "spot area" first. I'm suggesting the possiblity of using those two partially or totally depending upon as needed since you are using a DA PC and won't be building up the kind of heat a rotary produces.

The AIOX2 is mainly to ensure you've evenly applied the product over the entire area.

What pads are you using? I'm thinking the DACP and IP via yellow LC pads, FP via white and AIO via black

Speaking of IP and DACP, are they similar in abrasiveness/results? Or is one more abrasive than the other?

According to a chart some people put together I once saw, DACP and IP are similar in aggressiveness. I've found IP to give better results than DACP on my Audi paint but that's definitely not to say DACP is a terrible product.
 
Thanks, everyone.

I was doing some touch-up paint and wet sanding with 1000 grit. That's when I saw the leveled paint & knew what I wanted to see. Although, I was not about to wet sand the whole car.

Yea, Meg. #4 w/rotary... I'm sure it would do the job but I' new to this and want safer process. I have time right now.

Bill, I was thinking exactly about the process you proposed until I read IP had same abrassiveness as DACP. I try not to get too many items at once but my guess is IP polish should be added after DACP cutting. Then the next time I do the process, the surface will be in reasonable shape so drop the first process step.

As you can see I need to get proper foam pads.

BTW I use my 1991 Range Rover (wht-single stage paint) and 1997 Tahoe (Black with clear coat) as test vehicles. That's another discussion but if I get porsche right they will follow along.
