#9 and AOI necessary?

I'm getting ready to use AIO for the first time. I have minor swirls and scratches that I have to get rid of. I wanted to know if it is necessary to use #9 first, or will AIO have the same effect?
 
IMO #9 has more swirl removing ability than AIO. Even though it says on the bottle of AIO that it is non abrasive I have removed marring with it and it cleans up compounding haze pretty good to. I would try AIO first and if it can't remove the defects move up to #9 or something with even more cut if need be. Always use the least abrasive products needed to get the results you want.
 
Thanks, but if I did start with AIO first and I didn't get the right results, would I need to wash the car again w/ dawn before applying the #9?
 
Why would you wash with Dawn after trying AIO? Just use the #9 and it will strip anything on the paint. AIO does leave some protection behind but nothing that #9 can't remove easily.



I don't how bad your marring is but AIO and #9 are very mild and won't remove serious defects. You may actually need something with more cutting ability than #9.
 
Yeah, most people underestimate how hard it is to remove marring. If I were gonna use the K twins, I'd at least use 3M PI-III MG (pn 05937/39012 depending on size) first. That's my mildest go-to polish for cars I'm gonna use Klasse on.
 
So AIO will strip out #9 fillers, and #9 will remove the acrylic protection of AIO? Why would you use them together?

If you were going to use them together you would use #9 to remove minor defects and AIO as your pre wax/sealant cleaner. #9 has fillers that AIO will remove but #9 also has some cutting ability to remove minor defects.



#9 is very mild it might remove your defects depending on how bad they are. Might have to go with something with more cut. Just have to try and see what works . Always use the least abrasive approach to get the job done.

"Always use the least abrasive approach to get the job done", is very good advice.



If you need to step up to something stronger and like the Meg's line I suggest #80. The next step up in aggressiveness from there is DACP (#83).
